San Jose City Council Member Ash Kalra has written an op-ed for the San Jose Mercury News (published October 6) in which he explains how preserving Coyote Valley is consistent with California’s climate change goals, will protect vital wildlife corridors between the Santa Cruz Mountains and the Diablo range, and will safeguard our drinking water aquifer, which is vulnerable to pollution from industrial development because of the porosity of the soils in the valley.  Ash Kalra is  a candidate for the 27th Assembly District and has been endorsed by Sierra Club California.
