How Josephine County floods

Riverine flooding from heavy precipitation dominates Josephine County, supported by NOAA Storm Events Database records showing 16 floods compared to 4 flash floods over the last 30 years. Historical events illustrate this pattern, such as the January 2012 incident when very heavy and sustained precipitation caused widespread flooding across Southwest Oregon. Similarly, the December 2005 event caused both the Rogue River at Grants Pass and the Applegate River at Wilderville to exceed their established flood stages.

Federal insurance claims data indicates that property owners located within FEMA Flood Zone A should pay the most attention, accounting for 53 claims with an average payout of $16,817 and an average recorded water depth of 10 inches. Properties in Zone X_SHADED also experience significant impacts, averaging 20 inches of recorded water depth across 6 claims with an average payout of $18,017.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Josephine County

If a building in Josephine County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
