Towpath diversion is required so need to apply for this (4 weeks) – likely not to start until mid-August at the earliest Area K – planning submission is on hold due to design issues. Options have now re-visited and discussed with CMBC planners last week. They have confirmed their position and next steps are to meet with affected resident to discuss options Area L1 – planning is still on hold due to requiring Listed Building Consent – designers are working on a heritage statement to be submitted alongside the planning application Area L2 – planning has now been granted. We are awaiting cost from VBA for a walled option to rear of Tillotson Holme bungalows.
