Again you’re missing the overall need for STABLE/CONSISTENT pedestrian traffic. Convention goers and a few business people traveling in from the burbs every day isn’t enough to convince a developer that their store will succeed. You have to think about the casual every day person after 5pm living and becoming a part of the downtown fabric. We haven’t reached the tipping point where developers are now confident the downtown population can support a store. Yeah 3 years isn’t much time considering how far behind we were in overall infrastructure and development. Especially for being the 4th largest city, our downtown was very outdated and neglected. Now that Post HTX is kicking off and Houston Center is redeveloping, it’s a welcome sign letting us all know that downtown is really starting to take off. There really is not set time. Downtown is obviously showing new signs of life as each new project takes off and many more continue to finish. This also isn’t the nearsightedness we saw for so many years back in the late 70’s through the 90’s. Houston is finally developing in a more organized cohesive way with more thought in to overall quality of life. Not to mention the more noticeable national spotlight that this city has missed out on for so long.
