‘Moor Lane’ flooding. Are the risks being underestimated?

The Environment Agency published a useful online tool to help you assess the flooding risk to your property. It can be accessed at:
Flood Assessment Tool

So I had a look at the map for our general area:

Now lets turn on the flood maps…

We are potentially an island!

But lets not worry because its a 1:1000 chance of occuring.

That sounds like long odds until you factor in the impact of flooding if there is an increased level of building and concrete hard surfaces deposited in the area.  So what will happen then?

Im not sure but remembering these scenes from a few years ago do any of us really want to find out?
