St. Johns Flood History
St. Johns in north Portland faces risk from the Columbia Slough to the north and Columbia River backwater in high-water years.
Primary Flood Cause
Columbia Slough flooding and Columbia River backwater, with low-lying streets staying under for days after a major event.
St. Johns-Specific Risk Factor
Backwater rises slowly and leaves slowly. Days of standing water is a different drying job from a flash flood that drains overnight.
Common Water Damage Causes in St. Johns
- ✓Johnson Creek flooding during atmospheric river events, inundating residential streets in the Lents and Woodstock neighborhoods several times per wet season
- ✓Columbia Slough overflow affecting low-lying north Portland communities near Kenton and Cully during sustained winter rain
- ✓Chronic roof leaks and wet rot in aging cedar shake and composition shingle roofs from Portland's 150-plus consecutive days of measurable rainfall each wet season
- ✓Landslide-driven debris flows into homes on the West Hills and Mt. Tabor slopes when soils reach saturation during multi-day rain events
Insurance Tip for St. Johns Homeowners
Oregon's Insurance Division requires standard homeowners policies to cover sudden water damage but explicitly exempts slow seepage and landslide — two of the most common Portland-area claim types. Oregon homeowners on West Hills or other steep terrain should know that landslide damage is excluded from both homeowners policies and NFIP flood policies, and separate earth movement coverage is difficult to obtain from Oregon carriers.

Do you handle flood damage restoration in St. Johns?
YesWhen the flooding started inside the house: a burst pipe, a failed water heater, an appliance line, a sewage backup or a sump pump that quit — that is the flood damage restoration crews in St.
