Unacceptable street cleaning

Whilst I appreciate the importance of maintaining the roads and pavements for both safety and to prevent unnecessary maintenance, the council do retain a duty of care for users of the streets. Marlborough Road has just been cleaned by maintenance staff using blowers to remove debris from trees. Unfortunately many of the cars, including my sons, has been left in an unacceptable state following the works. See photos for examples. Maintenance should not cause undue nuisance to residents, and it’s frustrating to see that the staff carrying out the works consider the state a number of cars have been left is acceptable. I would like reassurance that staff are notified about this and there is not a re occurrence elsewhere in the city. Kind regards Ed
