Coastal developments at risk
Key Points | Report Card | Technical Information | Data
Beaches have changing shorelines that naturally move from year to year. Some years the sand on a beach may build up, while other years it may be eroding away. In many areas on the Coromandel Peninsula coastal development has occurred very close to the sea, not allowing for natural shoreline movements. In these areas development can be threatened by coastal erosion. This indicator looks at the number and capital valuation of properties and dwellings at risk from coastal erosion, now and in the future.
This indicator shows that:
- When beach shorelines naturally fluctuate, houses that have been built too close to the sea are threatened.
- On the Coromandel Peninsula about 920 properties are estimated to be at risk from coastal erosion over the next 100 years, due to potential sea level rise. Of these, about 670 properties are currently at risk.
- The number of properties and dwellings at risk from erosion has increased since 1995.
- The total value of property likely to be affected to some extent by coastal erosion over the next 100 years on Coromandel Peninsula beaches is approximately $850 million.

- The data for dwellings were collected from 1995/1996 and 2002 aerial photographs.
- The data for properties were collated from the Thames-Coromandel District Council.
