In Spain the provision of a dropped kerb is charged for annually - not just when it is installed. The fee is about 130 euros per annum, which includes the cost of providing yellow lines and a sign prohibiting parking across the dropped kerb and enabling offenders to be towed away by the police. It's not a fit and forget deal, where once a dropped kerb is installed, it is there in perpetuity. the benefits of introducing a similar scheme in London could be - more money for local improvements and/or a reduction in the number of 'live' dropped kerbs - with increased road space for on street parking, reinstatement of front gardens and improvements in the street scene. Is this a fair swap?
