Portland, Oregon - Cityscape

Cityscape

Portland straddles the Willamette River near its confluence with the Columbia River. The denser and earlier-developed west side is mostly hemmed in by the nearby West Hills (Tualatin Mountains), though it extends over them to the border with Washington County. The flatter east side fans out for about 180 blocks, until it meets the suburb of Gresham. Rural Multnomah County lies farther east. In 1891 the cities of Portland, Albina, and East Portland were consolidated, and duplicate street names were given new names. The "great renumbering" on September 2, 1931 standardized street naming patterns, and changed house numbers from 20 per block to 100 per block. It divided Portland into five sections: Southwest, Southeast, Northwest, North, and Northeast. Burnside St. divides north and south, and the Willamette River divides east and west. The river curves west five blocks north of Burnside and in place of it, Williams Ave. is used as a divider. The North section lies between Williams Ave. and the Willamette River to the west.

On the west side, the RiverPlace, John's Landing and South Waterfront Districts lie in a "sixth quadrant" where addresses go higher from west to east toward the river. This "sixth quadrant" is roughly bounded by Naito Parkway and Barbur Boulevard to the west, Montgomery Street to the north and Nevada Street to the south. East-West addresses in this area are denoted with a leading zero (instead of a minus sign). This means 0246 SW California St. is not the same as 246 SW California St. Many mapping programs are unable to distinguish between the two.
