The structural stability of a hoarding should be achieved with the least impact upon the width and openness of the footpath. Counterweights or columns are required to be designed as architectural features which are visually integrated within the hoarding design. The preferred arrangement is the provision of isolated column / counterweight units, rather than continuous fences between the columns. Columns and / or column / counterweight units are to be located with a minimum spacing distance of 4 metres along footpath areas, wherever practicable. Columns and / or column /counterweight units shall be located at equal spacings wherever possible unless this would be of detrimental impact upon the public domain. The minimum setback for the kerb shall be 250 millimetres from the kerb face. Longitudinal cross bracing may be used to ensure the stability of the hoarding and must be integrally designed with the structure. The number of cross bracing bays shall be minimised and restricted to bays where pedestrian movement is not impeded. The size of all secondary structures below deck level (excluding columns) is to be minimised. O
