Johnson Creek's record is the region's most documented small-stream flood history: 1964's largest flood on record, December 2015's highest recorded peak flow, and dozens of out-of-bank events between.
What should Kelly Creek homeowners know about the creek?
That it's earned its reputation honestly — Johnson Creek rises fast in sustained rain, and the mapped floodplain through south Gresham is drawn from real events, not caution. Homes near the corridor should know their flood-zone status (it determines whether rising-water coverage requires a flood policy), their lot's drainage path, and how their crawl space behaves in a saturated month.
Away from the creek, southeast Gresham's semi-rural edges add well-and-septic-era properties and long private drives — details that shape both risk and response access.
What weather does this side of the metro get?
The Gorge's exhaust: east wind that drives winter windstorms and the 'silver thaw' ice events east county knows too well. February 2021 was the benchmark — the worst storm in PGE's history with east county at its center — and January 2009's winds toppled trees from Gresham to Troutdale. Tree strikes, roof damage, and the rain that follows through the opening are the storm-season loss pattern; same-night tarping is the counter.
How does response work out here?
