Annex 7 - Engineering Specifications

      2.5. Deployment of navigation buoy(s) at each site and signage in accordance with permit
           conditions.
      2.6. Works to be undertaken in accordance with the Project Restoration Plan.
      2.7. Monitoring and Maintenance, as required (refer Note 4.)
      2.8. Works may need to be adapted in response to climate change, depending on monitoring of
           habitat health.


3.     NOOSA RIVER FISH HABITAT AREA, MATTERS OF STATE ENVIRONMENTAL SIGNIFICANCE &
       MARINE PLANTS

      3.1. The objective of the works is to restore oyster-dominated ecosystems to the Noosa River
           estuary including within the Noosa River Fish Habitat Area.
      3.2. Two of the Phase I Restoration Sites, Tewantin and Goat Island, are within the Noosa River
           Fish Habitat (A) Area. The Noosa Sound East and Noosa Sound West restoration sites occur
           outside of the Noosa Fish Habitat Area. The Phase II Restoration Sites have not been selected
           but will be within the Noosa River Fish Habitat Area (except for any further works in Noosa
           Sound restoration sites).
      3.3. Works to occur within the identified Restoration Zones, within 30m from shore, in water
           depths less than 2m below MLWS. The exception to this is the Tewantin site where works are
           proposed on existing rocky substrate, or in the future where otherwise approved in writing by
           MSQ.
      3.5. Phase 1 works results in temporary impacts to sparse marine plants at Tewantin site only.
      3.6. Works are NOT to impact on existing terrestrial vegetation (including vegetation within
           mapped MSES).
      3.7. During construction, plume is to be minimised and monitored visually to ensure no impacts to
           adjacent marine plants. Turbidity monitoring to be undertaken in the event that it extends
           within 5m of mapped seagrass beds (Refer Project Restoration Plan Section 6.4).


     4. MONITORING & MAINTENANCE

      4.1. Restoration substrates to be monitored periodically and after major storm events in
           accordance with the Project Restoration Plan.
      4.2. Maintenance to be undertaken as required. This may include:
           · Reprofiling and/or placement of additional rock on oyster reef patches to reinstate design
             levels and profiles after expected settlement has occurred. Ideally this would occur 12
             months after deployment but may be subject to timing of other works. Where limited
             natural settlement of oysters is experienced (nominally <200mm) and the crest remains
