Alexandria, VA · Alexandria Zoning Ordinance
The CDX zone (shown as CD-X in the ordinance) is applied to areas adjacent to the downtown CD zone that can accommodate greater density than CD. Building height is set by the Old Town North Small Area Plan rather than by a figure in the zoning ordinance. Common in the transition zone between Old Town and Braddock Road, and along the waterfront. Mixed-use development with ground-floor activation is the norm.
