Scripps News spoke to Urban Planning Professor Vinit Mukhija about the partially built high-rise buildings in downtown Los Angeles that were covered by floor after floor of graffiti earlier this year. The tagged buildings, part of a planned luxury complex abandoned years ago after funding dried up, stoked a national debate over development priorities, including how governments can put abandoned or vacant properties to good use. “The problem does seem to exist that there are too many hurdles for the local government to come in, acquire this project — not leave it empty, stalled for five years — and build something more socially beneficial out of it,” Mukhija said. “This should be an opportunity to make it into the kind of housing we want more than luxury housing. If there’s any housing we want more than luxury housing, it is affordable, non-market-rate housing.”
