Great question. You have plenty to choose from, what's yours?
One website that got me thinking on the subject of increasing the wealth of localities was the blog Strong Towns. I think you've shared an article of theirs. It's pretty straightforward, libertarian-leaning economics applied to the funding of construction projects, like the observation that the federal government attracts jockeying local politicians with sexy spending projects that leave the maintenance bill at the feet of state and local governments (who are woefully underestimating said maintenance's expense). But here's a sample: A Utah Republican might have the best urban transportation plan. It's a timely article considering that infrastructure is one of the things everyone vaguely wants to accomplish and Trump is pawning off on Congress to get done. That article got only one share, but this one had hubski buzzing.
