Urban damages
(residential, commercial and industrial)

Urban damages in the Johnstone Rivers system are concentrated in the Innisfail region and Mourilyan. However, this analysis also includes damage to residential properties outside of these townships such as smaller communities and farm houses.
The damage to urban areas is principally to property and can be categorised into residential, commercial and industrial sectors.

* A PMF (probable maximum flood) was not modeled. The total damages estimate for the PMF was calculated assuming a flood level 2 m higher than the 100 year ARI flood level. Neither the damages estimate now the flood level assumption should be quoted.
