In December 2018, the following works programme was published on the planning portal (see attachment). The planned start of the Tennis Courts was in January and allotments in May. Much of the POS was due to be planted and seeded in March & May, clearly this has not happened.
Work on the tennis courts restarted in May after a near 12 month delay and are progressing well.
I don’t have any updates outlining why work has not started on the general POS for you, but I may well write to Deborah Smith or Andrew Maclean to get the latest information (EDIT: Andrew replied and said he will update when he knows more. Deborah Smith is out of office until Thursday 30th May).
Your Ward Councillor, Andrew Maclean’s contact information is here.
