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-high

Design category D

Very high seismic hazard — at or near a major active fault. Very strong ground shaking is likely and the most stringent seismic-design provisions apply. A site-specific ground-motion study is typically required. The ASCE 7 Seismic Design Category here is D. (Short-period design value Ss ≈ 1.61 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.
