I think it would be considered part of the Rosemont neighborhood. Maybe John Roberts can weigh in; that's not too far from his 'hood.
JDP, now Parque Unidad, is located in an area served by the Rosemont Neighborhood Association, and is considered part of "The Rosemont Neighborhood". Like Fairmount, Rosemont consists of several additions and/or subdivisions of the city. The addition or subdivision in which the park actually sits is the Blanton's Addition.
