That's exactly what happened in Ashburn. Loudoun County VA is currently meeting pretty much its entire operating budget with data center tax revenue, and property tax rates have been going down for years. More importantly, Loudoun went from being the fastest growing county in the US, borrowing money and building roads, schools, fire stations, etc. at a fierce clip, to a much more maintainable population growth curve (= more compatible with residential sprawl).
