Green Light for Red Light District?

Today's WaPo article on initial negotiations by the city to buy out South East landowners at the future Nationals stadium includes this tidbit:

Some businesses have special needs, however. For example, Siegel owns a gay porn shop, which city regulations would prohibit from moving to certain neighborhoods. Mitten provided him with a map of the city that showed where such businesses are allowed to apply for a license.

Hmm, I'd be curious to see if that map overlaps the proposed Beaverhausen gay enterprise zone.
