@kpixtv: Floodwaters inundated roads and businesses in Mill Valley and Sausalito on Tuesday, prompting police to warn drivers to avoid flooded sections of Miller Avenue and Redwood Highway Frontage Road. A driver whose car stalled in a flooded underpass had to be rescued by firefighters, while a Sausalito business owner reported about 6 inches of water inside his shop and said flooding has forced other nearby businesses to leave.
