We live on a flood plain that last flooded in the 1940's when there was a massive snow fall that all melted in one day.They then built an embankment that holds it back. Job done. (we hope)
Then me and my missus come along and buy our home in 1981 in this small village and never even thought about the river over 2km away. Yes we should have checked but it was rare to see flooding in the county we live in back then and you never heard of it like you do now. Nowadays it is an automatic reflex to check.
I only found about the flood when looking at old photos on show in the village hall. There are 180 homes here and it was only the half a dozen nearest to the river that got flooded. Fast forward to 2007 and we find we are in a red area
But here is the point of my rambling post, we had to fight to stop the local authorities trying to grant planning permission for another 30 houses just down the lane from us. They seem to look the other way and let things pass despite what the future may hold.
