".......are they forcing the timber companies to repair the damage?"

The answer depends on what you call damage. If upgrading roads, disconnecting ditch water from streams, replacing culverts that block fish passage, side cast pull back and abandoning or upgrading stream adjacent parallel roads, then the answer is yes. If the question is in reference to old debris torrents and slides then the answer is no. I've looked at hundreds of debris torrents and slides and there's really nothing that can be done other than stabilize and revegetate the slope.

I don't know if that answers the question completely, but hopefully it clarifies some things.
