HOW MANY DOWNTOWNS DOES HOUSTON HAVE? The list of Houston neighborhoods with potential to be mistaken for Downtown by outsiders, Blake Mathews of KHOU writes this week, is long, and includes at least “Uptown (Galleria), the Texas Medical Center, Greenspoint, Greenway Plaza, The Woodlands and perhaps even Westchase.” So what makes a Downtown? Mathews runs through some factors for consideration, ranging from the city’s population density center (which falls somewhere west of Downtown) to total office space (Uptown has less than downtown Houston, but more than downtown Denver) to building height (with a specific shoutout to the Williams Tower, pictured here.)
