Portsmouth is a neighborhood on the North Portland peninsula. Its boundaries are the railroad cut on the west, Lombard on the south, Chautauqua on the east and Columbia Boulevard is on the north. Portsmouth has a lot to offer the citizens that live in and visit the area, including Columbia Park, pictured above. As the neighborhood continues to grow in many ways, neighbors have a lot of hope for this work in progress! *Also, please be patient as we build our new website, we are in the process of adding information. If you feel something is missing, likely we have not put it in yet, again....work in progress!
