One of the previous presentations talked about the fact that when the original act was put together you had bridges, dams, and those kinds of things, which were impediments to boat traffic, commercial or otherwise. That was in 1882, and things have changed since then. When you get into dealing with that definition, if you change that up, there are other kinds of structures that might be impediments as well.
As well, when you have department staff who have to administer that, they have no flexibility, because those works are clearly defined, so they have to deal with that as specified. So if you change that definition of work to allow the exclusion of minor works, then that allows more flexibility in dealing with it.
Coupled with that are some prescriptive directions for the responsibilities of the officers, so they don't have too much latitude in coming up with new and creative ideas, which has been one of the problems we've had in the past.
I don't know if that helps to clarify it.
