I can only speak for my own city, but the cost of building out new roads and infrastructure for new development is paid for not by property taxes, but by the building permits for the development. They actually just had a city council meeting outlining the expected growth over the next 5 years, its expected cost, and the resulting fees for building various types of residential and commercial development.

So the article is correct, that property taxes do not pay for it all. But that is not the only source of revenue.
