Question to the Department for Transport:

To ask the Secretary of State for Transport, what proportion of the route of Phase 1 of High Speed 2 has been surveyed.

Where access to land has been secured, physical surveys have been made possible on over 80% of the route. ‎In those locations where this has not yet been possible, desk based research (for example, using data sets provided from Statutory Agencies, Local Authorities and local Wildlife Trusts) and aerial surveys have been undertaken. The results of these are detailed in the Environmental Statement for Phase One, published to accompany the deposit of the hybrid Bill and the subsequent Additional Provisions.
