There is boundless documentation that would be of value if released publicly - road maps, for instance, meteorological data, buried conduit details. Some of this is already available ("Dial Before You Dig", bom.gov.au, etc). But make it "out there", and easy to get access to the raw data (in almost any freely usable format), and people will find ways of using it that nobody ever thought of. Some stuff that's currently available (eg. RF tower information from ACMA) is "available" but nearly useless, as it's too hard to find what you want to know. Putting raw data out there makes it possible for other people to do the interfaces for you. As for licensing, make it Public Domain. We pay taxes, and those taxes pay workers that made those plans/datasets/etc. So, make it freely available back to the public that made it possible in the first place.
