                 8.6 TPZ S TANDARD M I TIGATION M EASURES
                 Where groundworks are carried out adjacent to or encroaching into the TPZ areas the
                 following mitigation measures and procedures should be implemented where deemed
                 appropriate and should be supervised by Consult Arborist.

                 •    Where possible the excavated ground, including the cut roots, will be covered/backfilled
                      with quality topsoil locally sourced or a sandy loam/river sand with low organic matter, as
                      guided by AS 4419—2003. Australian Standard™ Soils for landscaping and garden use.
                 •    An application of a seaweed-based soil conditioner/plant food can be applied to the topsoil
                      as per the manufacturer’s guidelines. Monthly applications are recommended for the
                      duration of the project.
                 •    Ground protection measures are to be installed/used when access to the TPZ is required
                      to undertake construction works. All ground protection measures are to be discussed and
                      agreed upon with the Project Arborist prior to installation. These are to include but are not
                      limited to: ply sheets, geo fabric, thick mulch layer.
                 •    When required supplemental watering with a water cart or sprinkler system can be used
                      to retain adequate moisture levels in the soil.
                 •    The Project Arborist is to advise and oversee all mitigation measures works being
                      undertaken to retained trees.

                 All tree works, and tree protection measures, are to be guided by industry best practices and
                 the relative Australian Standards which include but are not limited to:
                  • Australian Standards AS4970-2009 Protection of trees on development sites
                  • Australian Standards AS4373-2007 Pruning of amenity trees
