It is the intention of Leith Central Community Council at its meeting of 19 September 2016 to discuss whether it wishes to call upon the City of Edinburgh Council to introduce controlled parking to the whole of Leith.
In this case, the whole of Leith was clarified as being Leith Ward 13 & Leith Walk Ward 12, the same area as Leith Neighbourhood Partnership. A map can be viewed here.
There are two petitions from the same person: one pro and one anti, to gauge opinion. So far the anti petition has the most signatures.
