Tree overhanging the road and entangled with power lines in an unsafe manner. Multiple neighbors reported concern on NextDoor, and the adjacent homeowner is apparently elderly and requires nursing care, and isn't able to drive the process.
After reporting to Redwood City, RWC identified that the tree in question is on the county easement and therefore responsibility of San Mateo County.
As SeeClickFix hasn't provided another mechanism to report, I've used Illegal Dumping - Sidewalk as the closest analog. My Post to Neighbors hadn't received a county response after 2 days.
Tree needs to be trimmed so that it is safe before the next high wind.
