In flood insurance claims here that reported a flood depth, the average was 6 inches.

From the storm reports

Coastal Flood · Nov 6, 2025. A strong low pressure system supported by a negatively tilted upper-level trough drove a cold-frontal boundary through the region supporting a period of high winds. This system coinciding with the arrival of Perigean Spring Tides (also known as King Tides) also led to localized coastal flooding.

Coastal Flood · Dec 14, 2024. The combination of high astronomical tides, large surf, and rainfall resulted in flooding of highways and roads in low-lying areas near Willapa Bay.

Flood · Dec 5, 2023. A strong atmospheric river brought heavy rains on December 5th which led to minor river and urban flooding across portions of southwest Washington. Clark County and Cowlitz County saw landslides, along with minor river flooding, including the Cowlitz River at Kelso and the Grays River near Rosburg. Portions of the Willapa Hills and south Washington Cascades received 12 to 16 inches of rain over a 5 day period begi…

Flood · Jan 6, 2022. The second in a series of strong Pacific fronts brought another round of heavy rain and resulting flooding of mainstem rivers draining the coastal mountains and interior of southwest Washington. Coastal flooding also occurred at some coastal communities as a result of high astronomical tides combined with high river levels and high seas.

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.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Pacific County

If a building in Pacific 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.
