The Home Office has refused to rule out further Channel migrant landings in Gosport or Portsmouth despite furious local protests.
Dinghies have crossed from Normandy three times in the past six weeks, with migrants brought ashore on two occasions in Hampshire - where they were met by hundreds of anti-migrant activists.
After Hampshire Police racked up an £800,000 policing bill dealing with the unrest, Gosport Borough Council passed a motion calling for the town to be excluded from any future disembarkations.
But the Home Office has refused to rule out the possibility, raising the prospect of a fresh local backlash.
A spokesman insisted there were no plans to process migrants at Fort Blockhouse, a former military site in Gosport. Instead, arrivals will be taken to the main processing centre at Manston, near Dover, for security, ID and health checks.
The spokesman said the Home Office had 'established contingency plans' to deal with small boat arrivals in Hampshire, but refused to comment further on 'operational processes or contingency plans'.
'Where circumstances permit, the Government will seek to engage relevant local authorities and operational partners in advance,' they said.
'The Border Security Command works around the clock to protect our border and will continue to detain, check and process every small boat arrival.'

Hampshire Police and Crime Commissioner Donna Jones has complained to Home Secretary Shabana Mahmood about the cost of dealing with regular anti-migrant protests and asked her to ensure landings in the local area 'do not become a regular occurrence'.
Mrs Jones said she had received no response to an initial letter sent after the first incident on September 6, when hundreds of protesters blocked roads in Portsmouth in a bid to stop coaches carrying 140 migrants from Eastney Landing.
Just over two weeks later, masked protesters descended on Gosport marina after reports that migrants were due to be brought ashore there.
Tensions flared again on October 4 when 149 migrants were brought into the town aboard two RNLI lifeboats after a 70-mile journey from Normandy.
Mrs Jones has sought details of discussions between the Home Secretary and the French interior minister, particularly over whether additional French resources will be deployed to prevent crossings along the increasingly used route from Normandy to Hampshire.
The Tory politician has said the landings are having a 'huge impact' on policing.
'At all three events, officers were abused, assaulted and filmed, live streamed on social media alongside assumptions about their motivations, when each and every one of those officers were deployed with an absolute commitment to upholding the law and keeping the peace,' she said last week.
'The cost of the policing operation so far since the first small boat arrival in Hampshire is now over £800,000.
'I have made a formal request to the Home Office for a full reimbursement and a commitment to reimburse all future deployments relating to small boat crossings, including protest activity.'
'I once again call on the government to ensure that landings on the Hampshire coast do not become a regular occurrence and that I am included in further meetings between the Home Secretary and ministers in order for me to fulfil my responsibilities on behalf of Hampshire and Isle of Wight residents.'
Several people have been sentenced for their roles in the unrest.
Del Somerville, 42, of Paulsgrove, was sentenced to two years in prison for violent disorder. Deano Ryan and Justin Dixon, 22 and 50 respectively, both received suspended sentences for the same charge.
Shannon Dodds, 32, and Sally Pearson, 31, were also handed suspended sentences after admitting assaults on police officers.
Alongside Fort Blockhouse, Gosport is also home to Haslar Immigration Removal Centre, which is undergoing a major expansion to accomodate 600 beds.
Seven jobs are being advertised at the centre as the Government presses ahead with plans to reopen and expand the facility despite fierce opposition.
The roles, which are graded at executive officer level within the Civil Service, will involve working directly with detained migrants, providing updates on their immigration cases and monitoring their welfare.
It marks another significant step towards reopening the former detention centre, which closed in 2015.
Under the Home Office's proposals, the first phase of the development would create accommodation for 130 detainees, before a second phase increases capacity to 600 across three-storey accommodation blocks.
The department's recruitment advert describes the jobs as an opportunity to make a difference to people being held in immigration detention.
It states: 'This is a rewarding and varied role where no two days are the same.
'You will engage with people from diverse backgrounds, make a meaningful difference during a challenging period in their lives and develop valuable communication, decision-making and problem-solving skills within a supportive team environment.'
