San Mateo County Employees Retirement Association SamCERA was founded in 1944 by the Board of Supervisors to provide retirement, disability and death benefits to employees of the County. SamCERA administers these benefits for all permanent employees of the County of San Mateo and the San Mateo Mosquito Abatement District. SamCERA operates as an independent public agency under authority granted by Article XVI of the Constitution of the State of California, the County Employees' Retirement Law of 1937 [commencing with Section 31450 of the Government Code of the State of California (also known as the 1937 Act)]; and case law applicable to public pension plans.
