No. Encapsulation has always been an approved method for dealing with lead paint on buildings not under renovation. Likewise, there is no need to deal with asbestos located in areas of buildings where it is sealed off and not disturbed, my own high school had a wing that was sealed off because they no longer needed the space and it contained asbestos flooring and ceiling tiles. It is only because of the necessary renovations, that the encapsulated lead or sealed off asbestos need to be removed, before they are driven into the air by the demo crew.
Maybe in California? Public school enrollment here has been on an ever-upward trend, for many decades, with no sign of turning negative.
Our own kids have always been in private school, and the low enrollment of all of our local private schools is a real problem, in terms of keeping programs going and keeping costs from climbing too badly. COVID helped, a lot of people left public school for a year or three starting in 2020, but almost as many have moved back to the public schools, today.
