I live near HOP and I am against a CPZ. It was also discussed about 7 years ago to the point where the council leafleted the street. A figure of £120 was discussed. Who knows what it could end up costing and I already pay enough to drive thanks.
Besides once a street has CPZ it simply pushes them onto the next street.

The convenience of having a car far outweighs the hardship of being unable to park right outside my door every now and then.
