Wiehle Ave. development called vital to Dulles Rail

One of the most promising changes Virginia officials have suggested to trim the ballooning cost of the rail extension to Dulles Airport is having a developer pay to build the garage at a Reston station instead of the public.

It’s a fairly straightforward plan — a company would gain the right to redevelop nine acres of Fairfax County-owned land on Wiehle Avenue in exchange for building a parking facility budgeted to cost $40 million to $45 million.
