D.C. Mun. Regs. tit. 11, r. 11-2900
The Union Station North (USN) District is a Unique Location District created to implement the Comprehensive Plan and other public policy goals and objectives.
Unique Location Districts are intended to apply to single large sites that require a cohesive, self-contained set of regulations to guide site design, building height and bulk, or other aspects of development.
The USN District recognizes the unique characteristics and development constraints of the site and provides for appropriate, site specific methods for the measurement of height and density.
The USN District shall constitute the Zoning Regulations for the geographic area referred to in § 2901.1. Where there are conflicts between this chapter and other chapters of this title, the provisions of the USN District shall govern.
When used in this chapter, the term "Transportation Way" means any piece of infrastructure, the intent of which is to convey people or goods from one place to another. Examples include, but are not limited to, sidewalks, stairs, elevators, fixed guideways for transit, and streets. Transportation ways may be either on, above or below ground, and may be either publicly or privately owned. Transportation ways do not include internal components of any portion of a building.
