What would you do?

What would you do if your property was flooded?

Are you prepared?

Even if you feel you live in a community with a lowrisk of flooding, remember that anywhere it rains, it canflood.

Just because you haven't experienced a flood in thepast, doesn't mean you won't in the future.

Flood risk isn't just based on history; it's also basedon a number of factors including rainfall , topography,

flood-control measures, river-flow and tidal-surge data,and chan es due to new construction and develo ment.
