Off-route effects for HS2 Supplementary Environmental Statement 3 and Additional Provision 4

The effects of the October 2015 amendments to the HS2 Phase One bill on areas away from the line of route.



This volume reports any new or different likely significant off-route effects arising from the revised construction assumptions, new environmental baseline information and amendments within the Additional Provision 4 Environmental Statement (AP4 ES).

For example, additional land for ecological mitigation at Langley compared to those reported in the main ES, as updated by the Supplementary Environmental Statement (SES), SES2 and SES3. The AP1, AP2 and AP3 amendments are also taken into account, where relevant.
