People's Republic of Brockley

The new coalition in Whitehall is planning to introduce the right for local people to hold referenda on issues of their choice. It's been suggested that the main issues this could cover are council tax, and housing and planning proposals. But what would the voters of Brockley choose to hold a Lewisham-wide referendum on?
Suggestions in the comments please ... you never know, if we can come up with a really good one, BC might petition the council for it, once the new powers are introduced.
