Base Flood Elevation

Base Flood had been defined only as the 100-year or the one percent annual return frequency flood. For the purpose of the Sacramento County Floodplain Management Ordinance the base flood is determined using best available information including the highest water surface elevation from any source of flooding determined by engineering analysis, measured high water, or Flood Insurance Rate Map (with floodway encroachment).​
