Major Corridors Development Tracking
One of the pillars of Arlington’s planning and smart growth strategy is to focus high-density development along major transportation corridors while preserving lower density in residential neighborhoods. These reports document trends in Arlington’s primary planning corridors — Rosslyn-Ballston, Richmond Highway, Columbia Pike and Langston Boulevard.
