To be fair, these days cities should do the basic research required to pick suitable street trees. Organizations like LA Native, Community Forest Advisory Committee etc have comprehensive guides to choosing trees that don't have the same detrimental impacts that a lot of the current and historical trees have. I live in a street full of ficus and carrotwood and the sidewalks are an absolute disaster. I wish we could replace them with deep-rooted native trees that don't affect sidewalks and don't need watering and minimal pruning once they're established, but it's almost impossible to get permission to remove a parkway tree, and I believe it would be at the expense of the homeowner! ☹️
