New Zealand is generally recognized as a leader in managing public assets and developing them to realize value and get the best ROI for citizens from those assets. And, they've been at it in a formal way for a while. See this report (from 2013!) for how they got started and how they provide accountability and transparency to improve asset management. 

I am offering up this admittedly dated report because I think if offers a good primer on how governments in the U.S. could get started on this important, but under-explored, topic. I am very interested in hearing what your government might be doing or thinking about starting on this topic - I think the potential benefit to citizens is enormous.
