Here’s what I found on their website, under the heading;
“Task Force Green”
Graffiti eradication – support to other organisations (Council and non-Council) continues as a low profile but immediate response to remove graffiti from prominent public sites. It is hoped the promptness of its removal discourages its reoccurrence.
So it seems the council are just “hoping” the problem will go away. I am guessing that there is no facility, or plan for a facility like a wall, to be available to artists. The vision of these, great folk in power is quite breathtaking. We will wait and see..
