Campbell Section 5 - Works Approval Project Ref: 110029Prepared for the Land Development AgencyFigure 5.7 – Swale as dry creek bed2. STREET SYSTEMD – Stormwater from the new street network will be harvested by rain gardens medians,areas of permeable paving, or piped into the retention basin. This water will be filteredthrough vegetation in the bioswale wetland before release into Lake Burley Griffin. Refer toAppendix 5 for a schematic that forms the basis for the design.3. BLOCK SYSTEM – BY SUB-DEVELOPERSE – Sub-developers of the Blocks will need to apply for NCA Works Approval and complywith the Building Code of Australia (BCA) incorporating sustainability into the design. It islikely that rain water captured from roofs will be stored within the blocks for reuse in toiletflushing, car washing, and watering of landscaped areas. These strategies to reuse roofwater are outside the scope of the Campbell Section 5 project and are included to illustratethe typical WSUD arrangements in a completed urban development. Some of theserequirements could be included under deed lease agreements for the sale of individualblocks.5.4 BiodiversityThe site currently consists of grouped plantings of Conifers and deciduous exotic trees clustered atthe edges; however, there is a limited range of species, with no locally indigenous speciesrepresented, and a mix of exotic weed and nuisance trees. Some native grassland is present butgenerally, the ground cover consists of exotic grassland weed species.The proposed park will support a range of specific planted environments, to increase biodiversityand habitat opportunity. Local indigenous trees, shrubs, grasses and wildflowers will be part of themix, forming an extension of ecologies present in Legacy Park and the hills beyond.November 2012 Cardno 27
