Cheryl Gillan said members of the HS2 Select Committee were made fully aware of the “unity of opposition” to the project in Bucks this week.

Four members of the Select Committee – currently hearing evidence from petitioners opposed to the controversial high speed rail proposals – visited Mrs Gillan’s constituency on a site visit on Monday.

They met with residents who discussed their concerns at the impact building work on the proposed line – set to cut through the Chilterns Area of Outstanding Natural Beauty – would have on the area.

Committee members had been due to meet a group of residents in Chalfont St Giles, but were unable to reach them as the lane taking them there wasn’t wide enough for their bus to pass along. The lane is due to be used by construction traffic during building work.

Campaigners have been calling for the entire length of the line through the Chilterns to be built underground in a tunnel; something that is not currently being considered.

Mrs Gillan said Committee members had become fully aware of the issues affecting Chiltern residents during Monday’s visit, which had spelt out the impact HS2 would have on the area.

She said: “No amount of looking at maps and plans can match the reality of seeing at first hand where HS2 will run and what impact it will have on the Chilterns. “No photograph can equal the sight of the Chilterns Area of Outstanding Natural Beauty (AONB) in the full glory of summer.

“Reading a document cannot convey the thoughts of people who see their homes and lives affected by the HS2 project. People from every community affected had done their utmost to show just what a devastating impact it will have.

“The landscape itself became a silent witness, showing the way that the current bored tunnel would emerge on the crown of a hill in an ancient woodland; the woodland, hedgerows and the ancient Saxon lanes that would be destroyed; and how the fragile chalk streams and rivers, the subject of so much conservation work, would be threatened.

“The visitors saw a brown trout jumping; a black swan on the pond at Little Missenden; and a red kite appeared like magic, soaring over the village of Hyde Heath.

“This, the only AONB on the HS2 route, deserves better protection.

“Councils, communities and environmental groups, with my support as their MP, demonstrated the unity of opposition. Their view is that the current plans do not go nearly far enough to protect the AONB. They disagree with the view of HS2 Ltd that the current mitigation is sufficient. Only 45 per cent of the HS2 route is currently in a deep bore tunnel. The remaining 55 per cent is above ground in shallow cuttings, across viaducts, or in the ‘cut and cover’ tunnels, the construction of which causes significant environmental damage.

“The Select Committee members heard about the full tunnelling options and all the work of local groups in providing evidence about these. The visiting MPs were also reminded about the incoming government’s pledges to preserve AONBs and fragile environments.”
