The city and region are noted for strong land-use planning and investment in public transit, supported by Metro, a distinctive regional-government scheme. Portland lies in the Marine West Coast climate region, which is marked by warm summers and rainy but temperate winters. This climate is ideal for growing roses, and for more than a century Portland has been known as "The City of Roses," and has many rose gardens – most prominently the International Rose Test Garden. Portland is also known for its large number of microbreweries, and as the home of the Trail Blazers NBA basketball team.

The city of Portland is governed by the Portland City Council, which includes the Mayor and four other Commissioners; and an auditor. Each is elected citywide to serve a four year term. The auditor provides checks and balances in the commission form of government and accountability for the use of public resources. In addition, the auditor provides access to information for all Council members and the public and issues reports on various matters of city government.

The city's Office of Neighborhood Involvement serves as a conduit between city government and 95 neighborhood associations, which are grouped into seven coalitions.

Portland and its surrounding metropolitan area are also served by Metro, the United States' only directly elected regional government. Metro's charter includes land use and transportation planning, solid waste management, and map development. It also owns and operates the Oregon Convention Center, Oregon Zoo, Portland Center for Performing Arts, and Portland Metropolitan Exposition Center. The Multnomah County government also provides many services to the Portland area, along with that of Washington and Clackamas Counties to the west and south.
