Many of our not-a-through-streets are subject to no-parking on Red Flag Days when winds are high and moisture content in plants is low.
In 1991, the Oakland Hills Fire destroyed 3,403 homes; 780 homes in the first hour. LAFD took notice of the similarities between Silver Lake and Oakland Hills. They added our neighborhood to the Very High Fire Hazard Safety Zone (VHFHSZ), raising brush clearance standards and, a few years ago, created Red Flag Day No Parking streets.
