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 ≈ 0.314 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.

This station records temperature and precipitation but not snowfall, so no snow column is shown. That is missing data, not a report of zero snow — Florence may well get plenty.

Growing season zone 8a
220 frost-free days
Last spring frost around March 27, first fall frost around November 3. 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.
