The Sheriff's Department has opened an $8-million station at 21695 E. Valley Blvd. to serve the growing population in the Walnut-Diamond Bar area. Phone numbers are (714) 595-2264 and (818) 913-1715.
The area had been served by the sheriff's station in the City of Industry. As part of the reorganization, the San Dimas Sheriff's Station has become a local station, run by administrators in Walnut.
