Last update on the American University campus plan for 10 years, we promise (probably): The proposal to convert the underutilized Tenley campus into AU’s law school was approved Monday by the Zoning Commission. Last week, the commission okayed the biggest proposal—a new campus that’s being built on an eight-acre parking lot. Meanwhile, the Tenley campus has been a bone of contention between neighbors and AU since the purchase of the land more than 25 years ago. At the time, AU promised not to develop the land for fear of offending neighbors. But neighbors saw the law school as little more than A) a cash cow for AU and B) a threat to their street parking. But times and the university’s needs have since changed, and AU managed to convince the commission to support the plan.
