The LA_City_Hall should have been at least 500' tall, but its only 454'. That still makes the Los_Angeles_City_Hall one of the taller ones around the planet.

The agenda to not permit any building in LA to be taller than City Hall was the case for several decades. Even Melbourne, Sydney, Brisbane & Perth weren't allowed to have buildings taller than the LA_City_Hall for a long time. Of course it took until the early 1970s for Vancouver to allow a building to be a little taller than the LA_City_Hall.
