I live on an unadopted road which is therfore not maintainable at public expense but is the responsibility of the frontages. There are some 24 private residencies who all contribute to the "maintain the road" fund but there is a block of 16 council flats at the top of the road that contribute nothing. We now need to spend a large amount on road maintenance what steps can we take to ensure the council will contribute for the block of flats which makes up by far the biggest by length frontage
