On 1 June I first drew the Council's attention to this problem, a leak in the water supply to the adventure playground which has created a green and slimy patch just inside the Park. Because this poses a slip hazard Glendale have kindly cleaned the area a few times, but the root cause of the problem remains.
But good news now (we hope). Paul Bailey at the Council (firstname.lastname@example.org) wrote yesterday "I have arranged to meet the contractors on site tomorrow to determine the works required, with the work to commence soon after".
It is unclear as yet whether the works will require the temporary closure of the bridge.
