The tent city near the 60 complete with generator, rope lighting and a disco ball got cleaned out late last year after one of the domiciles south of the 60 and along the back wall of the storage place caught fire. from Whittier Narrows north it's clear now, with just the few unobtrusive regulars north of the dam that have been there for years. Last fall before the rains came there was a concerted effort to clean out the camps in the riverbed down around Firestone, complete with Hazmat suited cleanup crews.
There's a likely end game for the SART camps like the SGRT 60 camp, but given the compact and crowded nature, it could with the wrong wind conditions turn into a multi-casualty event if someone kicks over a stove with the wrong wind conditions.
Don't think the local pols and other enablers have figured that into their virtue signaling.
