A resource consent is being sought for a huge new cleanfill tip on farmland beside SH58 just over the brow of Haywards Hill.
Winstone Aggregates is proposing to dump 1.7 million cubic metres of fill on the 13-hectare property over the next 55-60 years.
Up to 250 heavy trucks a day will be carting rubble, rock, concrete and soil to the site, the company says in its proposal.
The average traffic would be 44 trucks a day.
Residents on nearby properties are strongly opposed to the plan.
''We're hopping mad - who wants a tip next door,'' said Peter Sinke, one of a group of nearby Cecil Rd residents who have formed a group and set up their own website to stop Winstone's proposal.
They were concerned about their views and dust getting into their roof-supply water but the main issue was safety.
''It's also a major safety issue. There are a huge number of accidents on that road, we don't need 50 trucks an hour going into that site.''
Mr Sinke, who is a truck driver himself, said there were real dangers of trucks merging into fast moving traffic on SH58.
There were a lot of accidents on the road already - there had been seven since August.
There are also concerns that sediment from the landfill will flow down streams draining into the Pauatahanui Inlet, where runoff is silting up the shallow harbour.
The company says streams will be piped and runoff will be managed, although it is seeking consent to discharge sediment contaminated stormwater from the site.
Winstone Aggregates says its cleanfill tip at Dry Creek, at the foot of Haywards Hill is expected to reach its capacity by 2015.
The proposed new tip is on a gully just 4k up the road where a new intersection is proposed to allow trucks to turn off and onto the busy highway.
A short stretch of passing lane will be done away with to provide room for trucks to turn on and off the road.
The application has been lodged with Greater Wellington regional council, Porirua and Hutt City Councils.
Submissions close on March 6.
Regional council environment regulation manger Al Cross said it was bound to go to a resource consent hearing but it had to wait for submissions to see what the issues were.
It would be heard by a panel of commissioners appointed by the councils.
He said it was too early to say whether council officers had objections to the proposal.
