Description
Summary
This shapefile (polygon feature) contains flood elevation zones associated with the 100-Year Storm Flood Risk Zone. Flood elevation zones are an area with a single, uniform flood elevation that refers to the height (rounded to the nearest foot) that stormwater is likely to reach during a 100-year storm, measured from the San Francisco City Datum (SFCD). Parcels may have multiple flood elevations zones.
