Completely random example:
If someone wants to build a store and thinks they will do just fine with only 3 or 4 spaces, the code might require them to have 10. Now that they have to have 10 spaces, there might be more land used for parking than the actual store. It might even be more land than is available. Now you've gone from having a nice little neighborhood store to having nothing.
Key point there. Thank you for posting that. And in FW, that usually means a giant above ground garage. We have to be competitive on the amount of parking garages against the rest of the country in terms of scale.
