The MPFPD serves Menlo Park, Atherton, East Palo Alto and portions of unincorporated San Mateo County.
Deputy Chief Belville previously served as chief in San Mateo and Foster City; his 36-year career also included a stint in San Carlos.
He is the second temporary appointment made by the district in recent months. Interim Fire Chief Douglas Sporleder stepped in after Chief Harold Schapelhouman fell from a ladder at his San Jose home in mid-May. The chief is undergoing intensive therapy to recover from back injuries and the fire district does not know when he will return to duty.
The fire district also saw the departure of long-time marshal and division chief Geoff Aus at the end of May.
