If you read the casforum, Scirocco7 had posted the link to the planning portal and the response to the environment agency is there.
Having read it in full, there is only an extra 7 metre displacement with the new build and with the new work, is unlikely to be triggered unless a once in a 1000 year flood happens.
The planners have accepted that they will keep the gutters and drains clear.
In the event of one in a 100 year flooding, it is noted that this would be because of a failure the flood defences constructed by the environment agency.
So in conclusion, that’s the last hurdle for the ground part. I’ll have to read further to see if the axiom site has had any updates.
