The government of the City and County ofSan Francisco is defined by theCharter of the City and County of San Francisco, which is similar to the othercounties of California. Pursuant to its charter, San Francisco causes to be published several codified version of its ordinances and regulations, theSan Francisco Municipal Codes. Every act prohibited or declared unlawful, and every failure to perform an act required, by the ordinances aremisdemeanor crimes, unless otherwise specified asinfractions.[19][20]
San Franciscans also make use ofdirect ballot initiatives to pass legislation.
San Francisco's municipal authority extends beyond city/county limits through its operation of theSan Francisco International Airport and the vast tracts of land supporting theHetch Hetchy Water System.
The Department of Public Health works through two Divisions of the government - the San Francisco Health Network and Population Health and Prevention. The San Francisco Health Networks includes the health system with locations at multiple hospitals and primary care centers. The Population Health and Prevention Division focuses on the communities in SF and consists of three branches - Community Health and Safety Branch, Community Health Promotion and Prevention Branch, and the Community Health Services Branch.[21] On June 25, 2019,San Francisco become the first major US city to banElectronic cigarettes.[22]
In the 1890s San Francisco received heavy ship traffic from Asian cities that were currently dealing with the bubonic plague. In 1889, a ship from Hong Kong was found to have two cases of bubonic plague on board. The bodies washed up on the bay later, but no immediate outbreak occurred at this initial finding. In 1900 a city health officer autopsied a Chinese man and found evidence of the plague. With anti-Chinese feelings already running rampant throughout the city, the Department of Public Health quickly moved to quarantine Chinatown. Initially the quarantine was protested, not to protect the Chinese, but because of fear and doubt that the plague was indeed in the city. The mayor at the time, James D. Phelan, created the Board of Health, which included multiple doctors on the board. He demanded the Board of Health have 100 physicians search a 12-block area in Chinatown for more cases of the plague. After victims were found, the Board of Health publicly announced the plague, and the Chinatown quarantine was again set into place.[23][24]
Health officials shut down Chinese-owned businesses, and any Chinese or Japanese people attempting to leave the city had to first go through an inoculation with an experimental prophylactic developed byWaldemar Haffkine. This led to a court case between Chinatown resident Wong Wai and the Department of Public Health. Wai won the court case and the Department of Public Health was ordered to stop the inoculations, but city officials got support from the Board of Supervisors to continue.[25] Health authorities also attempted to set up a detention camp for those of Asian descent inMission Rock, but the idea was protested and canceled, partially due to fear about openly admitting the plague in San Francisco.[24]
Fear of the plague and prejudice against Chinese was so high that many city officials debated burning down Chinatown. The idea popular, especially since this had been done in Honolulu. To prevent their homes from being burnt down and break the quarantine, the Chinese rallied the Chinese Six Companies, multiple attorneys, and China's diplomat. Together, they were ultimately able to get the quarantine lifted again. This was again in part due to the government's fear of publicly confirming plague.[25]
Health authorities from 21 states eventually passed a resolution about California's neglect of duties to address the plague in San Francisco and threatened to close all trade with California. San Francisco businessmen reacted by assembling the Chamber of Commerce, Board of Trade, Merchants’ Association, Marine Hospital Service, new mayor George C. Pardee and various and civil rights groups to clear San Francisco of the plague.[24]
