I just posted this over on that Twitter feed page. But I went to the HEB mentioned tonight and saw no new construction as of 8-22-2022. However I noticed two locations with low traffic available parking slots.
One in the HEB fuel station area next to Texas Avenue, but it has a small power transformer.. I would think that would have to be upgraded before installing a Supercharger array of parking slots. And that would disrupt power to the fuel station and the Bank adjacent.
The other in the back of the store in a small area adjacent to the Water Tower that feeds the area.
There is a Large Power transformer about the size of a house in back of the store.. which means there is already large amounts of power feeding the area. And it doesn't block the truck delivery traffic flow or the stores loading dock, its offset closer to the Water Tower land with very high cement walls acting as a retaining wall. This might be the more likely.
Being in the back if the store it wouldn't disrupt the flow of traffic and they probably would not have to do much more than drop off the chargers and hook up their transformer supplies to whatever feeds the huge pumping mechanisms of the Tower and the stores power transformer.
The HEB fuel area is also littered with high curbing mediums all over the place that make it very difficult to drive without curbing your wheel rims. The back of the store does not have any curbs so backing in would be a lot less trouble. My best guess is the back of the store is more likely, unless they do major construction soon.
Everywhere else in the lot they would have to trench power cables and if they are going to make a Q4 online date that just doesn't seem likely.
Accessibility is (Only) possible from the South bound on Texas because of a major barrier down the middle of Texas. North bound traffic won't be able to scale the barrier and intersections are confusing enough and threatening enough no one will be doing Left-handed U-Turns unless they want to get into a major accident.
The Holleman Dr has only one very small narrow entrace near the store and its very easy to miss. And there are lots of curb rash mediums blocking and lining most of Holleman Dr. Someone one really went "nuts" a few years ago littering cement road curbs all over the area.. its very hazardous. Many are ragged and damaged now from all the damage these curbs have done to cars.
Park Pl is the more likely route people will have to take and exit on to Holleman Dr when they leave.
