Site 15 Remove or relocate to a new site upstream away from Optimal zone for oyster growth, within historical oyster
seagrass harvesting area. However, reef placement is over
recovered Halophila seagrass bed.
Site 16 Keep as per plan – fine sand/silt bottom Fine sediment easily re-suspended by wave action.
Pre-construction seagrass survey required Hard rock rubble below sediment surface
Monitor sediment accumulation Seagrass observed in close proximity to proposed
development footprint
We would recommend applying a development condition specifying that restoration units are
only placed on bare sand or mud substrate and not over existing mangrove propagules or
