Restoration criteria

Tidal Works            +30m            Within 250m = 4              Minimum distance of 30m maintained between tidal
(pontoons, jetties,    distance                                     works and oyster ecosystems. This measure reduces

                                                                    human activites, and also protects vessels and

                                                                    facilities.

Moorings               +30m            Within 30 m = 0              Minimum distance of 30m maintained between
                       distance                                     official moorings and oyster ecosystems to reduce

                                                                    consideration the maximum possible length of a

Foreshore Access       +10m distance   Within exclusion area = 0,   Minimum distance of 10m either side of public
(beaches and           maintained                                   foreshore access points maintained for ease of vessel
parks)                                 All other areas = 4          access to useable shorelines.

In-water urban         +5m distance    Within exclusion area = 0    Minimum distance of 5m maintained between
utilities (submarine   maintained                                   submarine cables and pipelines and oyster
cables & pipelines)                    All other areas = 4          ecosystems.

In-water transport     +30m            Within exclusion area = 0    Minimum distance of 30m maintained between in-
utilities (cross-river distance                                     water transport utilities and oyster ecosystems to
cable barges, ferry maintained         All other areas = 4          maintain safe operation of public transport services in
terminals, etc.)                                                    the river.

Seaward extent         <30m from       Within exclusion area = 0    Sites for oyster ecosystem restoration extend from

                                       All other areas = 4          from the associated shoreline to minimise impacts on

Water depth            <2m below       Within exclusion area = 0    Oyster ecosystems are only established in water
