Natural hazard

A map flag starts a specific investigation

Useful questions identify the hazard, its location, likelihood and consequences for people, the dwelling, the land and neighbouring property. The response may involve a different position, floor level, foundation, drainage design or specialist assessment.

Building and planning lenses both matter

The Building Act addresses erosion, falling debris, subsidence, inundation and slippage. Schedule 1A requires adequate provision to protect the land, building work and other property; if that cannot be achieved, the exempt pathway is unavailable.

Planning policy and district rules manage hazards such as flooding, landslips, coastal processes, active faults, liquefaction and tsunami according to risk. The NES-DMRU preserves applicable natural-hazard and other health-and-safety rules.

Collect evidence before detailed design

Combine current council maps and legends, the PIM, reliable site levels and the appropriate geotechnical, flood or coastal advice. Show the proposed footprint and hazard information together rather than treating a property-wide label as the final answer.
