Looking at the new where some had been hit by 3 times the normal
monthly rainfall falling in one day, I heard one victim complaining
that the local council were not helping him.

As if council members and their workforce were not stretched to the
limit / in the same boat (so to speak.) It is the worst peacetime
disaster that emergency services have had to deal with. (According to
C4 news.)

Heavy rains and flash floods undermine foundations. So from the ground
up, there is a lot of ground to cover; to coin a phrase.
