Tides: Medway Towns

Question
To ask the Secretary of State for Environment, Food and Rural Affairs what assessment she has made of the risk of flooding in the Medway towns from a surge tide coinciding with a spring tide; and what assessment she has made of likely changes to that level of risk over the next fifty years.
Answer

The Environment Agency assessment of flood risk is the likelihood of flooding occurring in any given year expressed as a percentage. The Environment Agency has assessed the tidal flood risk to the Medway Towns, considering a 5% (1 in 20 year event), 0.5% (1 in 200 year event) and 0.1% (1 in 1000 year event) chance of flooding, now and in 50 years time.This assessment has been made taking into account defences in place and the chance of peak surge coinciding with a spring tide.

Event type Number of properties at risk
2010 2060
5% (1 in 20 years) 70 240
0.5% (1 in 200 years) 255 770
0.1% (1 in 1,000 years) 700 1,155
