Climate resilience context

Mercer Island uses the Washington state resilience seed. The scenarios linked to this city page are flooding, wildfire and smoke, and straight-line wind storms; they are state-level hazards, not city incident claims.

  • flooding

    Washington flood risk includes atmospheric rivers, coastal storms, river flooding, landslides, and saturated crawlspaces.

  • wildfire and smoke

    Washington wildfire risk is highest east of the Cascades and in dry forest or grassland WUI areas, but smoke can affect homes statewide.

  • straight-line wind storms

    Washington windstorms often arrive with Pacific lows and saturated soils, leading to tree strikes, outage clusters, and roof-edge damage.
