History

The San Francisco Recreation & Parks Department began in 1871 when city officials responding to residents' demands for a large public park established the Park Commission to oversee the development of Golden Gate Park.  As San Francisco grew over of the years, parks and facilities were added all over the city.  Separately the city was running playgrounds, athletic fields, and recreational facilities under the direction of the Recreation Commission.  In 1950 the two commissions were merged and the San Francisco Recreation & Park Department was born.

Organization
The general manager is appointed by the mayor of San Francisco.
General Manager Phil Ginsburg oversees a staff of over 850 that includes gardeners, foresters, natural resource, pest management and nursery specialists, recreation and summer camp staff, lifeguards, park rangers, carpenters, plumbers, electricians, metal shop/welders and painters plus many many more from the historic headquarters inside McLaren Lodge at the east end of Golden Gate Park.

Commissioners
The Recreation & Parks Department is governed by a seven-member commission who are also appointed by the mayor of San Francisco to four-year terms.  The commission president is elected by fellow commissioners.  Commission meetings are held once a month at San Francisco City Hall. Current members are: Mark Buell (President),
Allan Low (Vice President),
Gloria Bonilla,
Tom Harrison,
Meagan Levitan, and Eric McDonnell.

Concerns have been expressed by park advocates about the lack of diversity of opinion on the commission and in the department, due to the fact that all of the positions are appointed by the mayor of San Francisco.  In the past, there have been efforts to change the selection process for commissioners.  A prior proposal included having three commissioners appointed by the mayor of San Francisco, three commissioners appointed by the San Francisco Board of Supervisors and one additional appointment agreed to by the mayor of San Francisco and the president of the San Francisco Board of Supervisors. This proposal had five votes on the San Francisco Board of Supervisors but was not able to get the sixth vote necessary to put it on the ballot.
