In California, Oregon, and Washington the state governments stripped cities of most of their powers related to zoning in regards to blocking conversions to mixed use residential. As long as there isn't heavy industry right next door (aren't crazy, no one wants Houston), mixed use residential zoning is hard for cities to deny.
Los Angeles has the problem (benzene, hydrocarbons, heavy metals) of all the oil wells, pipelines, refineries, crude oil storage, and other oil field infrastructure hidden behind facades all throughout the city. The city and county are an active oil field, something that should never have been approved when there is residential or light commercial literally 25ft away from camouflaged wells, pipelines, and crude oil storage tanks. Then again people over a century ago probably shouldn't have looked at the natural tar pits and thought to themselves "this is a great place to build a city".
New residential arguably is unethical in this situation, especially if it's lower income housing. Btw, this is the reason building new public schools has been almost impossible in Los Angeles and existing schools all have soil that if there were alternatives would mean shutting them down. Los Angeles and Houston are more alike than anyone likes to admit. Can't do the type of super fund site remediation (clean up) at the scale actually needed because it would mean tearing the city down to the bedrock to replace all the soil.
