There were two big examples we were thinking about when we did that. I think they were just on the borderline of connection here with urban conservation, but I think one could take it a step further.
As an example, we were looking at restoration activities in the Grand River itself, in order to improve assimilation of waste water rather than put massive amounts of money into another waste water upgrade that's really already at the limit of technology. That would be an example of using blue-green infrastructure instead of grey infrastructure.
The other example is that there's a big movement now towards integrating urban stormwater management with waste water management and water supply planning, linking them together around water reuse and what water is appropriate for what use, but I'm not sure our infrastructure funding programs go as far as to allow that kind of innovation.
You can imagine that in urban areas, especially now that they are all doing stormwater master plans to deal with their biggest problems instead of their site problems, there would be green and blue infrastructure needs serving both purposes here. It can be integrated together, but not in silos, as you say.
