sediment that extends landwards from the lowest astronomical tide to the line
of vegetation or bedrock or structure.
"beach fluctuation zone" means the range of natural locations a beach profile
occupies from its fully accreted condition to its fully eroded condition,
with--
(a) a landward limit defined by the escarpment resulting from the
erosion associated with a 1% storm event or a more extreme event of record,
whichever is the greater landward limit, and
(b) a seaward limit that is the
40m depth seaward of the highest astronomical tide for the open coast and 10m
depth seaward of the highest astronomical tide for estuaries or tidal coastal
lakes.
Note : The beach fluctuation zone ambulates as the coastline or
estuary or coastal lake foreshore experiences net long-term recession or
accretion due to changes in their sediment budgets.
"beach system" means the processes that produce the beach fluctuation zone and
the incipient foredunes and foredunes landward of the relevant beach.
(c) coastal lake or watercourse entrance instability,
(d) coastal
inundation,
(e) coastal cliff or slope instability,
(f) tidal inundation,
(g) erosion and inundation of foreshores caused by tidal waters and the action
of waves, including the interaction of those waters with catchment
floodwaters.
"coastal management area" means an area of the coastal zone identified in Part
2.
(b) activities or works to reduce the impact of coastal hazards on land
adjacent to tidal waters, including (but not limited to) seawalls, revetments
and groynes.
"coastal sediment compartment" means an area of the coast defined by its
sediment flows and landforms.
"Department" means the Department of Planning and Environment.
"ecologically sustainable development" has the same meaning as in section 6
(2) of the Protection of the Environment Administration Act 1991 .
"electricity supply authority" means a person or body engaged in the

for supply, directly or indirectly, to the public, whether by statute,

(b)
telecommunications,
(c) rail,
(d) roads,
(e) gas,
(f) sewerage systems,
water supply systems or stormwater management systems,
(g) airports, ports,
shipping and harbours.
"estuary" means any part of a river, lake, lagoon or coastal creek whose level
is periodically or intermittently affected by coastal tides, up to the highest
astronomical tide.
"foreshore" means the area of land between the highest astronomical tide and
the lowest astronomical tide.
"function" includes a power, authority or duty, and
"exercise" a function includes perform a duty.
"NSW Coastal Council" means the NSW Coastal Council established under Part 4.
"public authority" means a Minister of the Crown of the State, a State owned
corporation, an electricity supply authority, a Public Service agency, a local
council and any other public or local authority constituted by or under any

the limit of wave run up on the beach.
