With regards the notification for this. Letters were sent to all lease holders with 2 weeks notice prior to the expected date of clearance. Prior to that a notice was sent to all flats seeking views on clearing the carpark. A notice was also put on this forum at the same time and all notice boards. There has been a period of at least 6 weeks notice given delays from the managing agent. As far as I am aware that car park recycling area will be cleared today and it is very likely that any items moved back to parking bays will be cleared also. Given that you are terminating your residence in August I can only assume that you rent. Thus you need to address this issue with your landlord. In the mean time I would encourage you to remove your items today.
