Hello Duke,
Polite point of correction. Nothing has yet been decided about the "A" Boards or for that matter any street advertising furniture. The overriding factor here is that the Council has a legal responsibility to keep the highway/footway clear. Claims for accidents on footways are high - so the situation cannot be left as it is. They are also aware that "A" boards are free, effective advertising and they don't wish to stifle the initiative. So it is a bit of a conundrum for them.
Informing SMBC's opinion on this is that out of the 10 Authorities in AGMA, 7 of them have adopted/will be adopting a policy of zero tolerence.
For reasons best known by others Stockport has the most "A" boards in AGMA.
The Council has put forward a draft proposal of licencing and regulation (it was presented in draft at the last set of AC's) but this has a monetary cost to the vendor and has not found favour with local Councillors across Stockport, especially at a time when SMBC is supposed to be supporting the business community. The monitoring and enforcement of this scheme is also thought to be almost "unworkable" So at the moment it is back to the drawing board.
In my view Stockport will fall in line with AGMA and go for ZERO tolerance on this.
