State Mapping
The site is also within an Erosion Prone Area and Coastal Management District as shown in
SARA’s mapping below in Figure 4 - Coastal Management District and Erosion Prone Area.

As background for this report, the QLD Government Guideline: State Development Assessment
Provisions State Code 8: Coastal development and tidal works provides information on the intent
of the Coastal Building Line and the concept of coastal processes and this is provided below for
Council’s reference.
Coastal Building Line
Coastal building lines are declared in those areas that are already developed for urban purposes
and are highly vulnerable to coastal erosion. The intent of the coastal building line is to:
 provide a common alignment for building work;
 set back development from the coastline which reduces the erosion risk to people and
     property;
 provide space on the lot seaward of the development for construction of future erosion control
     structures wholly on the lot and not on State land.
Generally, no building work, including houses, sheds or swimming pools, would be permitted
seaward of a coastal building line. Only works for the protection of existing buildings from sea
erosion, such as seawalls, would be permitted seaward of a coastal building line.
Coastal Processes
Coastal processes are the natural processes occurring on the coast and in tidal water including:
   wind, waves, tides and currents which transfer energy to the coast and drive other
     processes;
   sediment transport to and along the coast;
     sediment accumulation or erosion onshore and offshore which builds or destroys landforms
       including foreshores, beaches, dunes, delta plains;
     the growth and spread of plants and succession of plant communities, especially where
       plants have a specific role in trapping sediment and building landforms (mangrove and
       dune colonizing grasses) and stabilizing sediments against erosion;
     changes in sea-level both temporary and permanent from weather events and climate
       change.
