The Council is to re-examine its contracts which cover spraying weeds on public highways.

The move, announced at the last Council meeting, comes in the wake of unprecedented levels of complaints about weed infested streets particularly in the west of the City.

At one point, even prominent City centre structures like Ouse Bridge were under attack.

It now appears that several streets – scheduled to be treated in a second wave of spraying – were missed.

During early October the Councils contractors walked the whole of the City spraying areas that needed attention.

They are also spraying round street furniture, poles etc.

The last Council meeting was told that the authority is considering letting a new spraying contract next year in conjunction with neighbouring authorities.

The Cabinet member was unable to explain why supervisory checks had not revealed – and remedied –the problem this summer.
