Lincoln Square, the new mixed-used development at Broad and Washington, incorporates almost every feature that a density-loving urbanist could want. At nine stories, it is tall enough to hold its own at that busy Center City intersection. Shops and restaurants (including a Target) ring much of the ground floor, which hugs the edges of the site in traditional urban fashion. The developers also managed to incorporate a historic train shed into the mix and give it a first-class renovation. They even made room for a generous outdoor public space, one that really does welcomes the public.
