Overlays that can apply
Mapped hazard and district overlays stack on top of the adopted code. These are the overlays recorded for Mississippi. They apply by parcel, not jurisdiction-wide, so confirm the parcel before assuming one is in play. Check CAL FIRE's fire hazard severity viewer and FEMA's flood map service.
