The City of Portland responds to urban gentrification through an investigation of noise sources within the boundaries of north Portland neighborhoods.

Abstract

The North Portland area is a vibrant community, supporting residential populations, a wildlife reserve, and an active commerce. As Portland continues to attract new residents and residential areas expand in North Portland, the conflict between the residential desire for a peaceful environment and the commercial requirement to efficiently conduct business become more critical. The sustainability of the North Portland residential communites relies on planning decisions based on a well‐defined understanding of the sound characteristics of the community. The City of Portland chose to study North Portland to better understand noise within its boundaries. The resulting noise mapping will serve as a tool for the City to use in future planning.
