Why South Waterfront faces sewage backup risk
Built for South Waterfront’s high-rise reality — shared-stack risk that a single-family-home page wouldn’t address.
South Waterfront is one of Portland’s newest and most vertically dense districts.
The neighborhood is served by the OHSU aerial tram connecting to Marquam Hill.
Its riverfront location means lower-elevation drainage conditions than much of the city.
Shared vertical stacks in high-rise towers mean a single blockage can affect many floors at once, and riverfront low-elevation drainage plus high occupancy density mean backup consequences scale differently here than in single-family neighborhoods.
