Seems to me that the State bears the preponderance of the responsibility in this. I say this because I would have to think that whenever a project is being submitted for review that it would be assigned a supervising official (SO). This SO would be responsible to work with whatever group leader, contractor or volunteer, to ensure that the government property and interests are protected. The SO would also be responsible to walk the project with other leads to ensure all parties are on the same page in order to avoid issues like this. SO would also be required to do a periodic walk through and keep proper reports on the project. If manning is such an issue for these agencies then volunteers could very well relieve some of their pressure when it comes to grunt work. But this would not relieve the agency of their oversight responsibility. Seems like basic project management.
We need pictures to clear this up. Pushed over trees could have been leaning alders that would have fallen in the road at some point. It's a lot easier to remove those trees when you have the equipment in there that after the fact. I doubt the trees they pushed over were 24" firs. I would also need to see the culvert damage. I agree that this seems to be written with an agenda.
The carnage and devastation in those picture is amazing.
