How Lincoln County floods

River overflow, coastal flooding, and urban inundation driven by atmospheric rivers and slow-moving frontal systems dominate the flood character of Lincoln County, where the NOAA Storm Events Database recorded 22 flood events over the last 30 years. Recent regional impacts are documented in events such as January 2021, when a series of slow-moving fronts brought heavy rain, high surf, and coastal, river, and urban flooding, and November 2021, when an atmospheric river produced river flooding enhanced by high tides backing up rivers and creeks in low-lying coastal areas. An additional atmospheric river event occurred in December 2023, dumping heavy rain that pushed streams and rivers to flood stage along the coast.

FEMA National Flood Insurance Program records indicate that residents and property owners in Zone A should pay the most attention, accounting for the highest volume with 313 claims averaging a payout of $15,366 and an average recorded water depth of 9 inches. Properties in Zone V also require close attention due to high severity, recording 36 claims with the highest average payout of $61,368 and an average water depth of 2 inches. Additional claims occurred in Zone X_SHADED (43 claims, average payout $9,871, average water depth 22 inches), Zone X (38 claims, average payout $14,982, average water depth 15 inches), and Zone X_UNSHADED (28 claims, average payout $18,338, average water depth 18 inches).

Where the flood claims came from

17% of Lincoln County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Flood · Dec 5, 2023. A strong atmospheric river brought heavy rains on December 5th which pushed many streams and rivers to flood stage along the coast, with minor flooding on many smaller streams and creeks across northwest Oregon. After moderate rainfall December 1st through the 4th, a very slow moving front dumped more heavy rain to the northern Oregon coast and coast range mountains. Area of the Coast Range received 12 to 16 inche…

Flood · Jan 13, 2021. A series of slow moving fronts brought periods of heavy rain along with strong winds. This resulted in high surf; coastal, river and urban flooding; landslides; and debris flows. As the front moved inland early on the 13th, a debris flow resulted in a fatality in the Columbia River Gorge. The front brought a burst of 35-50 mph winds to the Willamette Valley and southwest Washington interior resulting in over 100…

Flood · Nov 12, 2021. Heavy rains produced by an atmospheric river brought river flooding to portions of northwest Oregon and southwest Washington. In addition, high tide backed up rivers and creeks in low lying areas along the coast, enhancing flooding.

Flood insurance in Lincoln County

If a building in Lincoln 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.
