Gov. Gavin Newsom has a new strategy to eliminate the large, long-standing homeless encampments that have been a thorn in his side throughout his administration: Push cities to make them illegal.

The governor on Monday called on every local government in the state to adopt ordinances that restrict public camping “without delay.” He provided a hypothetical model ordinance that lays out exactly what he’d like to see banned: Camping in one place for more than three nights in a row, building semi-permanent structures such as make-shift shacks on public property, and blocking streets or sidewalks.
