Thanet council is due to issue a Section 77 notice to leave on Travellers currently based at Ramsgate Port.
A small number of caravans has been on the council-owned site since June 9.
Council officers have carried out welfare checks prior to issuing the notice to quit.
It is an offence for somebody subject to such a notice to fail to leave as soon as reasonably practicable or to re-enter the site within three months of the date on which the notice was given.
If the group do not comply with the Section 77 Notice, Thanet council will need to apply to the court for an Order of Removal.
A Thanet council spokesman said: “We are aware of the illegal traveller encampment that has recently arrived at the Port of Ramsgate. Officers from Thanet District Council are in the process of undertaking the necessary welfare assessments and will then issue the required notices. ”
Further settlements this year have taken place at St Nicholas, Manston Tesco, Dreamland, land by the Manston airport site and Jackey Bakers.
Providing Traveller sites – the law
The Housing Act 2004 and Planning Circular 01/2006, Planning for Gypsy and Traveller Caravan Sites, has put in place a framework which means every local authority has to identify land for the sites that are needed in its area. The Secretary of State has powers that can ensure that those sites are identified, and the Local Government Association (LGA) says local authorities should be proactive in doing so.
The LGA adds: “The provision of these sites removes a major cause of friction between the two communities – unauthorised sites and illegal camping.”
The nearest authorised sites to Thanet are at Aylesham and Canterbury.
