To my knowledge, there hasn't been. We did not include that in our report. I should point out that the assessment as to the condition was made by the department, and you're right: two-thirds were judged poor to fair. Obviously, depending on the condition, different actions would need to be undertaken. Some would be to restore; others could be to simply try to preserve it as it is.
So we're not aware. I don't know--the department might have done some more work on that--but I believe at the time of our audit there wasn't an overall costing of how that would be done.
