The San Francisco planning and public utilities commissions approved a $4.4 billion dollar plan to upgrade the Hetch Hetchy water system, rebuild the dam on the Calaveras River and allow the city to draw more water from the already endangered Tuolumne during drought years.
San Jose Mercury News: “The city’s planning and public utilities commissions approved the upgrade Thursday, saying it’s needed to keep the system safe in case of a major earthquake or drought.
The plan calls for numerous projects, including replacing a dam at the Calaveras Reservoir that is not seismically safe and laying more pipeline.
It also calls for drawing more water from the Tuolumne River during droughts, a proposal that environmentalists do not support.”
