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 high
Design category D
High seismic hazard. Strong ground shaking is expected over the life of a building. Substantial seismic-resistant design, detailing, and inspection are required by code. The ASCE 7 Seismic Design Category here is D. (Short-period design value Ss ≈ 0.898 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.

Growing season zone 10a
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.
