From the article:
Richmond’s own TriBeCa – a cluster of brownstone three-story homes on the easternmost edge of the Randolph neighborhood – has begun work on six more units, with nine additional detached homes planned next year.
The Lower Manhattan neighborhood’s name is an acronym for Triangle Below Canal Street, and its Richmond counterpart is short for Triangle Below Cary Street. Its inspiration is a triangle of land that is bordered by South Harrison Street and Grayland and Idlewood avenues.
It’s interesting that the article makes no mention of the Idlewood roundabout project, which should be starting construction also.
