Flood zone: it depends on the exact parcel
There is no such thing as a flood zone for a whole city. Two houses on the same street can sit in different zones, and it is the single fact here that changes most over a short distance. So this page does not guess one.
Earthquake hazard low
Design category B
Low seismic hazard. Earthquakes are infrequent and usually minor here, but the building code still applies light seismic detailing to new construction. The ASCE 7 Seismic Design Category here is B. (Short-period design value Ss ≈ 0.179 g — the standard headline measure of ground-shaking hazard.)
USGS Seismic Design Web Services (ASCE 7), assuming Site Class D — stiff or unknown soil. Real soil conditions can move the category either way.

365 frost-free days
Last spring frost around n/a, first fall frost around n/a. Roughly half of years see frost outside that window.

What this page does not tell you
- Nothing about a specific property — only the area around it.
- No flood zone, deliberately: that is parcel-level and this page would have to guess.
- Nothing about wildfire, radon, subsidence, soil or the building itself.
- Climate normals describe a typical year, not the year you are about to have.
