It comes as the council voted to charge a new "contribution levy" to local developers on Wednesday night.

The vote followed a heated community meeting between councillors and residents on Tuesday where locals vented concerns about the hundreds of trucks hauling clean fill through rural back roads.

"I think it's going to take someone getting killed on these roads before you do something," one resident said on Tuesday. "It's just money and dirt."

Wednesday's adopted plan would see the council collect a fee of the project cost on construction or subdivision projects if the cost of development is more than $100,000.

Developments between $100,000 and $200,000 would have to pay 0.5 per cent in contributions to council, as in $500 on a $100,000 project.

Projects above $200,000 would be charged one per cent.

Council documents said it expected the Yass region's population to grow by more than 10,000 people in two decades, requiring more than 4000 new homes.

On Tuesday, councillors and staff - including deputy mayor Nathan Furry - had gathered residents in Wallaroo outside Hall - to discuss the council's future operational plan.

Given the chance to ask questions, several residents expressed concern about the delay in the heavy haulage policy and said it was not enough to repair roads damaged by the excessive truck movements.

The council is having a new heavy haulage policy independently reviewed by engineers.

Yass council previously said Canberra construction companies were dumping thousands of tonnes of fill just over the border in NSW to avoid the high cost of disposal in the ACT.

This was often as rehabilitation works for eroded gullies on Yass farmland with developers saying they would fill eroded gullies.

A recent development on Kaveneys Road approved by council in December would have 90,000 tonnes of clean fill dumped on a Yass region farm. It would have cost more than $1 million in fees for the fill to be dumped in Canberra.

Instead, it would cost that developer $2110 in road maintenance costs, based off calculations which factor in the weight of the truck and the wear that would cause to the road.

But according to the development application, the weight factor for the truck used in the council's calculations was equivalent to what the Australian Trucking Association would classify as a half-loaded truck.

One resident told councillors on Tuesday that most development applications, when calculating road levies, had applied the wrong truck weight to calculations.

The new levy would see council charge 4.5 cents a tonne of payload a kilometre.

Hypothetically, if a fully loaded truck carrying 33 tonnes travelled down three kilometres of road to ultimately deliver 90,000 tonnes it would cost the person dumping the fill more than $12,000.

The new policy doesn't factor in how worn the road is or how suitable it is for trucks.

Residents on Tuesday said this would still not be enough to deter trucks and it would still be cheaper for developers to drive trucks an hour out of the ACT and dump fill than to dump it in Canberra.

The residents told councillors sharing the poor quality and narrow roads with trucks was dangerous.

"The number of trucks are well outstripping the amount of money you're pumping into these roads," one resident said.

Many of the residents approached by The Canberra Times after Tuesday's meeting would not provide their names for safety or privacy reasons, some fearing reprisals by developers.

Local Catherine Baird asked why developers always applied to dump exactly 60,000 cubic metres or 90,000 tonnes of fill.

"What is this magical number," she said.

"It's the typical size of a basin in construction," one resident said.

Ms Baird said she would often drive by the Yass council sign where a slogan reads "the country, the people".

"And sometimes I just want to graffito 'and the trucks'," Ms Baird said.
