The San Francisco Public Utilities Commission last week gave final approval for replacing the 85-year-old Calaveras Dam near Fremont and Sunol in the East Bay.
According to SFPUC spokeswoman Maureen Barry, the new $434-million dam project started bid advertising Jan. 31 with a pre-bid scheduled for Feb. 15 and contract award at the end of March. Construction is scheduled to start in the summer.
