Layer name: Railway_Infrastructure_and_Projects-HS2_P1_Safeguarding_Subsurface_GS

This is a polygon based dataset that shows the extents of the subsurface safeguarding areas associated with the HS2 project. Safeguarding protects land which might be needed to build and operate the HS2 railway from conflicting development. In locations where subsurface safeguarding applies, local authorities do not usually have to consult on applications for planning permission, unless the proposed development would extend below ground level. For HS2, subsurface safeguarding is usually put in place when the proposed line of the route is in a bored tunnel.

Layer name: Railway_Infrastructure_and_Projects-HS2_P1_Safeguarding_Surface_GS

This is a polygon based dataset that shows the extents of the surface safeguarding areas associated with the HS2 project. Safeguarding protects land which might be needed to build and operate the HS2 railway from conflicting development. Local planning authorities must consult on all planning applications they receive that fall within areas where surface safeguarding applies. For HS2, the land that is identified for surface safeguarding generally involves surface work and structures associated with the railway where the route is above the ground.
