Fairfax County is a suburb of Washington, DC, in Virginia. It borders the small urban county of Arlington and the historic city of Alexandria. It often trades places with next-door neighbor Loudoun County as the nation's wealthiest county.
In Virginia incorporated cities are politically completely independent of their counties. County law does not apply in incorporated cities (but may apply in incorporated towns); the only local law in incorporated cities is city law.
