NoPoCo is a backronym for

North Portland is a roughly thumb-shaped portion of Portland, Oregon. Its eastern boundary is N Williams Avenue and imaginary lines that extend that avenue northward to the Columbia River at about a mile west of PDX airport, and southward to the Willamette River at the Steel Bridge. The Columbia and Willamette Rivers form the other two boundaries. All the rest of Portland is divided into NorthEast, SouthEast, SouthWest, and NorthWest quadrants: North Portland is therefore known as Portland's fifth quadrant.

This web site is an umbrella that provides several Portland groups and individuals with an internet presence that they would otherwise find difficult to maintain.
