Yes they can, it happened to us.  We had planning permission from Roquetes to re-build an old mill.  When we re-submitted plans Roquetes sent them to Cat Aigua, which they hadn't before.  They refused permission for us to do anything on the site because of the risk of flooding....... in a water mill.  It cost us thousands before we had to abandon the project and start again elsewhere.

I'm so sorry to hear that.
So your'e not in the Barranc anymore ?
I don't know if you remember us, we have a finca further along the Barranc.
We chatted on here a few years ago  :-? when you were just starting your project on the mill.
We had trouble with planning too.
Anyway sorry for the hijack Steve
Cheers
