Extremely overgrown hedges and trees

Owner of 3 Maes y Nant has again left her trees/hedges to obstruct and take away pavement/gully access. She has been asked by neighbours, people attempt to use the path, pentyrch community council and Creigiau community council to cut these back. It's a danger due to holly growing out as well as brambles. Along with this there are trip hazards due to big roots growing out of the path and also slippery and prickly surfaces along the path. It's multiple accidents waiting to happen.
