Earthquake hazard, typical weather and growing season from public federal data. Population 41,757.

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 very-low

Design category A

Very low seismic hazard. Damaging earthquakes are rare at this location and design ground motions are minimal. Ordinary buildings carry essentially no special seismic-detailing requirement. The ASCE 7 Seismic Design Category here is A. (Short-period design value Ss ≈ 0.094 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.
