    Box 1: Example of effects of acquisition compared to non-acquisition
    The diagrams below show the difference in the loss value of two properties. One is acquired by
    Council in 2040, and the other is destroyed due to coastal erosion in 2070. Both properties are
    assumed to be valued at $2 million, would both have been destroyed in 2070 due to coastal
    erosion, and were both built in 2000.

5.1.5.        Option 7 - Changes to planning provisions to prevent development within the
              projected 2070 coastal erosion prone area

Under option 7, changes to planning regulations prevent development within the projected 2070
coastal erosion prone area. This leaves an estimated 66 properties, primarily within the suburbs of
Sunshine and Sunrise Beaches, with lot sizes potentially too small to undertake any rebuilding3 after
