V 1.0 Home Page Description of Portland's Street numbering system and layout. The city is divided into five sections as labeled on the map below. Burnside Street divides North from South Williams Ave.
Street numbers are odd on the North and West sides and even on the South and East sides.
An address may include an area designator, e.g. 900 NW Glisan. The same scheme applies to outlying suburbs - adjacent cities wholly within a section will have all their streets designated the same way, those that overlap sections, can have more than one designation. To ZOOM out.
