15. Dredging is to be undertaken in accordance with the Noosaville Concept Dredge management Plan (ICM, 2022).
16. Material is to be sand suitable for nourishment. Any unsuitable material encountered is not to be placed on the foreshore.
17. Dredging to be undertaken with suitable plant (e.g. small cutter suction dredger with cyclone).

18. Dredge areas are to target shoals in close proximity to the nourishment area and minimise dredge depth by targeting shoals.
19. Dredging is to target uniform extraction across wide area (i.e. avoid digging holes).
