4.2.1    Assessable Development
         Any proposed removal of marine plants/fisheries habitat associated with the project would be
         assessable development requiring fisheries approval.

4.2.1.1 Significant Residual Impact Assessment
         Under the Significant Residual Impact Guidelines:

           An action is likely to have a significant residual impact on marine plants where the
           impacts of the development shall result in:

           • public infrastructure works impacting more than 25m2 of fish habitat; and

               ○ temporary impacts are expected to take 5 years or more for the impact area to
                 be restored to its predevelopment condition; or

               ○ a proposed reduction in the extent of marine plants through removal, destruction
                 or damage of marine plants; or

               ○ fragmentation or increased fragmentation of a marine ecological community; or

               ○ adverse changes affecting survival of marine plants through modifying or
                 destroying abiotic (non-living) factors (such as water, nutrients, or soil)
                 necessary for a marine plant’s survival; or

               ○ alteration in the species composition of marine plants in an ecological
                 community, that causes a decline or loss of functionally important species; or

               ○ interference with the natural recovery of marine plant communities.

         Depending on the final design and construction activities, the proposal may result in the removal of
         more than 25m2 of marine plants.

         It is anticipated it will take 5 years or more for mangrove individuals to be restored to their pre-
         development condition. Saltmarsh species may restore to pre-disturbance conditions within 5 years.

         Provided the following recommended environmental controls are implemented, it is anticipated the
         proposal will not:

         • result in a permanent reduction in the extent of marine plants;

         • result in fragmentation of a marine ecological community;

         • adversely modify or destroy water, nutrients, or soil conditions necessary for marine plants;

         • alter the species composition or functionality of marine plant communities;

         • interfere with the natural recovery of marine plant communities.

         The following environmental controls will help minimise impacts to marine plants during construction
         and promote restoration of impacted habitats to pre-disturbance conditions or similar.
