Hazards and constraints
Flood, bushfire and environmental mapping — what it shows and what it cannot certify.
6 guides
Flood screen
A mapped overlay intersecting the parcel is a screen. It is not a flood certificate.
How to check flood risk before buying a property
Screen riverine, overland and coastal flood maps, then climb from overlay to council levels. A polygon is not insurance or safety.
Bushfire screen
Prone-land mapping is not a BAL. Construction cost sits in the assessment, not the tint.
How to check bushfire risk before buying a property
Separate prone designation, planning overlay, hazard and a site BAL. A map is not a construction rating.
Environment
Vegetation, koala, waterway and heritage layers restrict works. The name changes with the council.
Environmental overlays buyers should understand
Mini-references for biodiversity, vegetation, waterways, heritage, contamination, acid sulfate, landslip and coastal layers. Map is a trigger.
Condition, not verdict
Mapped is the start of a price and a plan. It is not a stamp that says walk away.
Why a hazard overlay does not make a property unbuyable
Worked examples of overlays that change a project and overlays that end it. No reassurance. Some constraints are severe.
Risk components
Hazard, planning, rental, market and building are different questions. They do not add to a score.
How to assess property risk before buying
Build a risk register for a lot: component, evidence, owner, status. Not a score. Unknown stays unknown.
One finding
Read a single adverse fact against the other nine checks, not as a moral verdict.
Why one red flag does not make a property bad
Case-driven reading of single findings, including a case where one issue kills the intended use. No motivational close.
