All the streets in Portland Oregon are designated with directional prefixes like NW or SW. This lets you know what section of town the homes are located. The North/South boundary divider is Burnside Blvd which runs the length of Portland near it’s center. The Willamette River separates the East and West sides of the city. Then to complicate the design there is a North Portland area known as the 5th quadrant. Take a look at the maps below and the highlighted Portland neighborhoods.
