The Department of Public Works is secretly the friendliest and most knowledgeable department in all of San Francisco. They design, build, operate, maintain, clean, green, and improve the city's infrastructure, public rights-of-way, and facilities. They are guided by the department's three-year Strategic Plan and their Climate Action Plan. Almost all the department employees spend time driving around the entire city and talking with everyone in the city government, giving them an unparalleled breadth of city knowledge.
