Housing in Olympia and where water damage starts
Olympia has about 26,795 homes, and half of them were built in 1982 or earlier. Population was broadly stable between 2020 and 2024 (+1.6%). It is a mixed housing stock: 48% of homes predate 1980 while 25% were built in 2000 or later. Older neighborhoods tend to see aging plumbing and water heater failures, while newer construction more often brings appliance hose, ice-maker and fixture leaks into finished drywall and engineered flooring.
Olympia climate and water risk
The nearest NOAA normals station, Olympia 1.3 S, records 59.0 inches of precipitation in a normal year. That is a wet climate by national standards, and the volume of rain puts steady pressure on roofs, gutters, window flashing and grading. The station averages 11.8 days a year with an inch or more of rain, the kind of day when gutters overflow and water finds its way through thresholds and window wells.
Disaster history in Thurston County
FEMA records 12 major disaster declarations covering Thurston County since 2000. 13 of the county's declarations on record were classified as floods. The most recent water-related declaration was DR-4906 (Severe Storms, Straight-Line Winds, Flooding, Landslides, and Mudslides), declared in April 2026. Before that: DR-4650, severe winter storms, snowstorms, straight-line winds, flooding (March 2022); DR-4539, severe storms, flooding, landslides, and mudslides (April 2020). Declarations mark the largest events; most household water damage comes from smaller storms and everyday plumbing failures that never reach that level.
