    Outcome in report

    THE TREE IS A LARGE BAY TREE IN THE BACK GARDEN OF THE ABOVE ADDRESS. IT STANDS VERY CLOSE TO THE SIDE WALL OF THE NEIGHBOURING PROPERTY WHICH IS THE REAR OF LLANDAFF INSTITUTE. THE BRANCHES ON THAT SIDE COMPLETELY OVERLAP THE ROOF, LYING ON IT OVER A LARGE AREA. THE TREE HAS GROWN TOO BIG FOR THE SPACE IT OCCUPIES, CASTING SHADE OVER A LARGE PART OF THE GARDEN AND TAKING UP MOISTURE NEEDED BY OTHER PLANTS. WE WISH TO HAVE THE TREE FELLED TO THE GROUND. ACORN TREE SERVICES HAVE ATTENDED AND ADVISED THAT THIS IS REASONABLE GIVEN ITS SIZE AND POSITION. THERE IS NO TPO.
