We have heard a lot from HS2 on Community Engagement. However this seems to be in theory rather than practice.
HS2 has been carrying out Ground Investigation Works alongside the river Misbourne near Shardeloes Lake. There has been no communication to say that this would be happening. They just arrived and started drilling. This has created a bloom of chalk particles in the Lake on last Friday and Saturday. The Environment Agency were informed and came on Sunday, but the bloom had dissipated.
