Glendale has good bones, but the entire west valley has lagged the east, that seems to be changing as a lot of manufacturing, logistics and distro is moving into the west valley and there are a lot of plans being floated for redevelopment of the various suburban town centers in Suprise, Peoria, Glendal, Litchfield Park, Avondale, goodyear all with various degrees of development plans by the city governments. Also the Stadium area is seeing some serious growth of both office projects that are actual multi story office buildings! Its wild!
It will be interesting to see how it goes as much of the cheaply available land in the East is developed (other than very far out exurbs) how that will change the economics and culture of the east/west divide over the coming decades.
Anyway, hope these west valley cities can benefit by developing their downtowns and town centers with nice local businesses.
