Residents of Boulder Creek’s Echo Lane neighborhood are seeking answers as the aging wooden water tanks—commonly referred to as the “Echo Tanks” by the San Lorenzo Valley Water District—continue to deteriorate rapidly. The tanks continue to lie in disrepair despite a $4.5 million grant from the Department of Water Resources’ Urban Community Drought Relief program. In addition, $1.5 million was given by the district for repairs. The plans called for replacing the outdated wooden structures and fire-damaged plastic ones with six new 120,000-gallon bolted-steel tanks. … These tanks supply drinking water to a large part of the San Lorenzo Valley community, but also provide critical water storage for firefighting during the area’s fire season.
