Chilterns HS2 Community Liaison Forum 

"Members of the public are invited to attend the HS2 community liaison forum at the Chiltern District Council offices. HS2 and their contractors will give a presentation on the current work programme and future plans for the local area.

This is an opportunity to hear directly from the contractors, to understand their approach to the work and to ask questions to the experts delivering the work on the ground."
