Joining San Francisco and San Jose, Oakland makes up one-third of Northern California's Golden Triangle. Founded in 1852, Oakland boasts of a diverse population, numbering more than 390,000 residents, a Mediterranean climate and thriving hip arts scene. The city is a hub for the port of San Francisco Bay, as well as for the business elite and the higher educated. Environmental policies have helped propel Oakland to stand among the top green economies in the US. The city is served by a mayor and eight council members, who oversee a budget of almost $1 billion. It is home to the NBA's Golden State Warriors, NFL's Oakland Raiders and national landmark, Lake Merritt.
