The American Diabetes Association reached a deal to shift its national headquarters from Alexandria to a new home in Crystal City. The association has signed a lease for about 70,000 square feet with Vornado Realty Trust at 2451 Crystal Drive. The association will be shedding about 15,000 square feet when it moves later this year from its current home at 1701 N. Beauregard St.

in Alexandria. That building, as it happens, is part of the Mark Center, a major beneficiary of the military's reshuffling.
