Protecting boundaries after bushfires

The location of property boundaries are reliant on three key factors:

  • plans of survey held at the Land Titles Office
  • permanent survey marks (PSMs) on site - typically steel or concrete marks buried in the ground
  • existing fence locations.

Preserve any evidence of a boundary following a bushfire, particularly when clearing fence lines.

Replacing fences

Damaged fences are typically replaced in the same location as the original fencing. Take care to preserve the original location through the clean-up phase. This could include placing offset marks before clearing the fence line.

The original fence might not be located on the true boundary position. Hire a licensed surveyor if you have any doubts about the location of the boundary.

Protecting permanent survey marks

PSMs are major reference marks placed by surveyors. They provide evidence of property boundaries and can reduce the costs of  remarking boundaries.

These marks form the basis of our GPS framework, which is used in construction, development, transport and agriculture.

In rural areas, PSMs are usually located in the road reserve, next to fencing at prominent road bends or intersections. They are often marked with a blue star dropper and red indicator plate.

Following a fire, the dropper is typically blackened and damaged, but usually visible.

The location of these permanent survey marks can be found on the SA Property and Planning Atlas.
