In a new working paper, Emily Hamilton examines the outcomes of an ambitious redevelopment plan passed by policymakers in Fairfax County, Virginia in 2010. Ten years after its passage, she evaluates how well the redevelopment policies lived up to their stated goals of generating more multi-family housing in the area and creating a walkable downtown area. Fairfax County is demographically similar to many other areas facing a crisis of housing affordability, but is currently on track to meet its target of adding 80,000 more residents by the middle of this century. It has been less successful in achieving walkability, however – largely due to the legacy car-oriented infrastructure and construction of the new metrorail above-ground.
