Why St Johns faces water damage risk
St Johns’ former-town, peninsula-geography combination is unlike any other neighborhood on this list.
St Johns operated as an independent town before its annexation into Portland.
The neighborhood is home to the iconic St Johns Bridge and Cathedral Park.
Its peninsula location sits near the confluence of the Willamette and Columbia rivers.
Legacy town-era infrastructure from before annexation, peninsula river-proximity drainage challenges raising flood and groundwater exposure, and industrial-adjacent utility corridors from the area’s shipping-era development all shape how water damage presents here.
