Volunteer to clean, green, and beautify Oakland! Each year thousands of people pitch in on a variety of projects such as litter and graffiti removal, landscaping, tree planting, habitat restoration, fire fuels management, and mosaic artwork installation. Public Works sponsors two annual City wide events for Oakland Earth Day and Oakland Creek to Bay Day. Public Works also supports MLK Day of Service, as well as volunteer projects throughout the year by groups and individuals looking to give back to their community.
