BORDON and Whitehill could be forced to accommodate more housing development if the South Downs National Park gets the go ahead.
In a letter to the town council, the Countryside Agency confirmed that the town will not be included in any proposed national park.
It was agreed the council would support proposals which would include the chalk ridges and would make the total area covered by a national park smaller.
Councillors believed Bordon could be pressurised into taking more housing development if other towns were in the national park and the boundary of the park stopped at the edge of the town.
Dr Chris Wain said: "I can see the development coming to us without any problem at all."
Basil Smith labelled the national park scheme as "empire building" and said: "We will get people wanting to build here and we will get the pressure of development here."
He said the Countryside Agency could be the planning authority, which could mean only a few representatives from East Hampshire District Council would be able to have an input on planning decisions.
Monday's planning and amenities committee was told that Petersfield and Liss were keen to be included in the boundaries of the park.
Clerk Linda Tiley said the two areas did not want the same development pressure which Bordon could face if they were excluded from the boundary of a national park.
It was proposed by Dr Wain that the town council should support a smaller area for the national park, which would then relieve some of the development pressure on the town.
In a unanimous decision, it was agreed to inform the Countryside Agency that the town council would support a smaller South Downs National Park.
