North Yorkshire Council's response to an unauthorised traveller site has been criticised as "ineffective" by a councillor.
Reform UK's Tim Grogan, who represents Monk Fryston and South Milford, has called for urgent changes to how the authority responds when land is occupied and developed without permission.
It comes after travellers set up on a four-acre (1.6ha) paddock on Betteras Hill Road, in Hillam, near Sherburn in Elmet, on 11 September.
Grogan's motion, which will be heard at next week's full council meeting, includes calls for new police powers, an out-of-hours provision for planning enforcement and urgent allocation of land to accommodate travellers when needed.
"The travellers arrived at the site with a convoy of trucks, industrial machinery, building materials, septic tanks and a mega tonnage of hardcore," Grogan said.
"They executed their entry on to the land with a cold, mechanical synchronisation akin to an operation of military professionalism."
According to the Local Democracy Reporting Service, he said the incident followed similar developments at Lumby and Biggin, also in North Yorkshire.
"I am not here to demonise the travelling community but what has happened in Hillam, Lumby and Biggin is wrong," Grogan said.
"I recognise and value democracy but this is neither. It is favouring individuals who break the law with impunity over those law-abiding rate payers who play by the rules."
However, Conservative council leader Carl Les defended the authority's response and questioned whether additional out-of-hours staffing would be justified.
After the travellers arrived at the site early on a Friday evening, Les said the council took action the following Monday, applied for an injunction in court mid-week and the case was heard on Saturday.
"We've got to understand what the time frame is in all this before we commit to having extra staff on duty over the weekend on the off-chance that something may happen," he said.
A report accompanying the motion acknowledged that the proposals would have financial implications, including extra staffing costs and potential expenditure on allocating land.
It also warned changes would require a full equality impact assessment and compliance with national planning legislation.
The proposed emergency police powers would require a change in the law.
Last month, a High Court judge agreed to allow the interim injunction to be extended.
The hearing was told that the occupants were planning to appeal to the Planning Inspectorate in a bid to remain on the land.
The injunction will remain in place until the outcome of the appeal.
