your valves should have a manual control knob. see if that opens the valve. Solonoid is the black thing on top of the valve. Problem could exist in the solenoid, the wires going to the solenoid or your timing box. attach a multi-meter to see if you are getting juice to the valve. i think you can replace a solenoid, but you might as well replace the valve as they are cheap and easy to replace.
Doesn't the sierra club take away your card if you have a sprinkling system? xeriscape is the dogma.
the santa fe home depot doesn't even sell sprinkling stuff.
