                      a.      The driveway must be constructed using Holcim Product Code QS32XDIA unless
                              prior written approval is obtained from Council;
                      b.      The driveway must be constructed so as not to concentrate stormwater runoff onto
                              neighbouring properties;
                      c.      Underground service conduits for water supply, electricity and any other services must

                              streetlights or other signage. The developer is responsible for any necessary relocation
                              of existing services to provide this clearance and must contact the relevant service
                              authorities and comply with their requirements in relation to these works.
                      (*Refer to Advisory Notes)
                      Earthworks and Retaining Walls
               24.    All earthworks shall be undertaken in accordance with the provisions of AS 3798 Guidelines

                      defined in Appendix B. Test results as required by AS 3798.
               25.    Fall protection must be provided to retaining walls that are over 1m high.
               26.    Slope and batters are a maximum grade of:
                      a.      1 in 6 where in proximity to waterbodies;
                      b.      1 in 4 for grassed areas;

                      d.      1 in 2 for combined structural engineering and planting solutions.
                      Stormwater Drainage
               27.    Appropriate scour protection must be provided at the outlet of all stormwater pipes including
                      temporary outlets.
               28.    Works associated with this permit must not adversely impact on the existing drainage
                      conditions on other properties (e.g. by blocking or interfering with natural overland flows).
               29.    Construction of all internal stormwater drainage works must comply with the relevant
                      section/s of Australian Standard AS/NZS 3500.3.

                      Regulation 2019) must not be released from the site or to waters within the site, or be likely
                      to be released should rainfall occur, unless all reasonable and practicable measures are
                      taken to prevent or minimise the release and concentration of contamination.
