1. EQC Increased Flooding Vulnerability CAG overview 22 July 2014

2. Outline EQC land cover IFV – what it is and what it isn’t General IFV criteria Flood modelling Assessment process Settlement process Next steps

3. 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 EQC Land Damage Cover

4. EQC land cover

5. 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.

6. 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.

7. 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.
