Marcus Yasutaki, Folsom's utilities director, presented the final Folsom Water Vision report to the City Council, describing a 50-year roadmap to secure the city's water supply and reduce vulnerability to a single-point failure.

"We have 1 single raw water pipeline from Folsom Reservoir to the city's water treatment plant," Yasutaki said, citing a high risk for that single point of failure.
