The issue was raised at the St Sampson’s parish meeting this week, as a parishioner asked if anything could be done.
‘It’s a devil to get rid of. It’s awful,’ she said.
Another parishioner pointed out that the site would have to be cleared eventually to make way for development, including a proposed new road.
There were fears that only the tops of the plant would be cut off, rather than the roots being dug out, which could cause an ongoing problem for any new houses built on the site.
Junior constable David Hannah, who lives in the Saltpans, said the seeds from the pampas grass blew all around the area and his car was often covered in them, which meant he was likely spreading them en route wherever he drove.
‘We’re trying to get on top of these things,’ said senior constable Joe Abbotts, but he admitted that it was ‘in States’ hands’ and expected to cost an estimated £100,000 to resolve.
The issue of roadside weeds was also raised by parishioners, with one asking about the possibility of following in the footsteps of other parishes by hiring a private contractor to keep the roads and pavements clean and tidy.
‘It looks diabolical,’ they said.
Mr Abbotts said the douzaine had been in talks with someone who was interested in doing a chemical-free trial whereby they would eliminate weeds manually and by burning but they were waiting to hear back.
It was unclear whether such an arrangement would mean extra charges for the parish ratepayers or be paid by the States.
Traffic & Highways is currently responsible for cleaning the roads, and some of those around the Bridge are cleaned on a daily basis.
Douzenier Jennifer Merrett said they would do their best to deal with problem areas if brought to their attention.
‘If there’s a particular road, do let us know and we’ll arrange for it to be cleared,’ she said.
