Cardiff Council say a new cemetery is needed in Thornhill or it will run out of burial spaces in the city by 2020.
There are over 700 burials a year at the current Thornhill site, and the council is proposing a new cemetery on council-owned land near the M4 motorway.
The proposed new site is 650m from the existing one at Thornhill.
Local and neighbouring councillors have had a briefing about the proposals.
“We understand there is obviously a shortage of grave space in the city, and I understand that there needs to be provision for this, but it mustn’t be to the detriment of the local business, local residents and also the traffic on and off the site,” said Jayne Cowan, Conservative councillor for Rhiwbina.
“We need to make sure that the traffic flow is monitored very closely, and that there is adequate screening for the shops and the neighbouring houses,” she added.
Conservative Councillor for Lisvane, David Walker says he’s concerned about plans to build the site in a green belt area.
“By tradition, building north of the M4 in that area has been opposed. Once you start breaking that precedent, people say: ‘Well, you’ve done that north of the M4, why can’t we do this?’, so that’s a slight worry I have,” he said.
The proposals will be discussed at a Cardiff Council Scrutiny Committee meeting this afternoon.
Cardiff Council were unavailable for comment.
