When it comes to parking, I think the Council is trying to create a problem which doesn't really exist. As far as I am aware, apart from the immediate vicinity of trains stations there are no problems with parking. People will still need cars to cover situations that aren't covered by public transport / cycling / walking, etc.
What will happen is that more front gardens will be paved over to create driveways. As for the environmental aspects of this push, why then on Bexhill Road are they proposing only one EV charging point for 130+ properties, chopping one fully grown tree to be replaced by a small young one? If the council really had environmental issues at heart, then they should be putting loads of EV chargers and lining the streets with lots of trees / plants. What about traffic calming initiatives, dealing with speeding, pavement parking, pedestrian crossings?
