York's battle against the floods
27 September 2012 Last updated at 18:52 BST
The river Ouse in York has risen five metres above its usual level to its second highest level ever.
A temporary bridge was built on Skeldergate in York on Wednesday to help people get in and out of their building and sandbags were put out to try to keep the water at bay.
Some people had to be rescued from the floodwaters by boat on Thursday morning.
