If you needed any further evidence that Northern Virginia has recovered from the recession faster than most, look no further than Tysons Corner. The Post’s Corinne Reilly had a great piece Thursday detailing how developers are lining up to build build build along the new Silver Line, as part of the plan to remake the sprawling mallscape into a walkable city. And for more detailed coverage of the evolving Tysons City, you should definitely be reading The Tysons Corner blog.

One of the original proposals for the new Tysons City was a big fat road right down the middle of Old Courthouse Spring Branch park, a 33-acre forest that is the last expanse of green space in the area. Residents organized against it and seemed to have convinced the Fairfax County Board of Supervisors that it was a bad idea. The board in November voted to ask planners to take the option off the table.

Now the Fairfax Department of Transportation has weighed in with a letter examining the idea of an exit ramp from the Dulles Toll Road down into the park, to connect with the big fat road (aka Boone Boulevard). Director Tom Biesiadny writes to the board in the letter below that his staff believes this option “can be eliminated from further study.”

The full letter is below, and the Board will take up this matter formally on Jan. 15. But both the transportation department and park authority have determined that this watershed and formally designated “resource protection area” needs to be, uh, protected. Are we done here now?
