Sections of the Sonoma Overlook Trail are damaged after a water tank overflowed during routine maintenance last week. Sonoma city officials say the water tank on Norrbom Road overflowed last Tuesday while divers were examining the tank for signs of corrosion or damage. The water flowed through a protected path on the Overlook Trial, causing it to erode. Officials say the trail remains open and hikers are not in any danger by using the trail. Maintenance teams will be out on the trail today fixing the damage.
