High Quality Content by WIKIPEDIA articles! The Sacramento County Sheriff's Department (SSD) is a local law enforcement agency that serves Sacramento County, California. It provides general-service law enforcement to unincorporated areas of Sacramento County, as well as incorporated cities within the county that have contracted with the agency for law-enforcement services. Currently only Rancho Cordova has such a contract with the department since the Citrus Heights and Elk Grove Police Departments assumed all police authority and responsibility for their communities in 2006.
