EQC Land Damage Cover

EQC land cover
  • Land
    • Under building
    • 8m around building & structures
    • main access within 60m of dwelling
  • Bridges and culverts in the land above
  • Retaining walls within 60m of building and supporting the building or land as above
increased flooding vulnerability
Increased Flooding Vulnerability

IFV is

  • a physical change to residential land, that is
  • a result of the earthquakes, which
  • adversely affects the uses and amenities of that land, by
  • increasing the vulnerability of that land to flooding events.

Changes to the insured land that result in it becoming more vulnerable to flooding as a direct result of the earthquakes are covered by EQC.

Not IFV
  • Flooding that occurred pre-earthquake sequence, or
  • Increases in flooding due to changes to offsite drainage due to earthquakes, or
  • Increases in flooding due to changes in streams and rivers offsite.
general ifv criteria
General IFV Criteria

The flood depth has increased by 200mm or more as a result of the Canterbury earthquake sequence, and

The flood depth has increased by 100mm or more as a result of a single earthquake event, and

The land has suffered observed damage as a result of the Canterbury earthquake sequence, and

The change in flooding vulnerability has caused the value of the property to decrease.
