The real issue with a new Walmart opening in Burbank should be the increased traffic that it will bring.
If you don't want to shop there, then don't shop there. If you don't want to work there, then don't work there. But the traffic in the area is going to continue to get worse than it already is.
The intersection at Victory and Burbank is a nightmare at rush hour and on the weekends, and traffic from the Golden State (5) Freeway south exiting onto Burbank Boulevard often backs up onto the freeway.
Hopefully, the city of Burbank is going to address this issue sooner rather than later.
