In 2004, current and former Placer County social workers reported that the county had an "unwritten policy" of homeless dumping, encouraging employees to send homeless individuals to neighboring jurisdictions--namely facilities in Sacramento County. The story was initially reported in the Sacramento News & Review and corroborated in an independent story in the Sacramento Bee. 
Based on this and other instances of homeless dumping in Sacramento, California State Assembly Member Dave Jones introduced Assembly Bill 2745, prohibiting hospitals from sending a homeless person to a facility in another county without that facility's consent. The bill became law in 2006 when it was signed by Governor Schwarzenegger and included in Section 1262.4 of the California Health and Safety Code.
