Dataset 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. HOW THE DATASET IS CREATED Additional information on the 100-Year Flood Risk Zone and flood elevations can be found on the Flood Maps website https://www.sfpuc.gov/learning/emergency-preparedness/flood-maps and on the Information Sheet https://www.sfpuc.gov/sites/default/files/documents/SFPUC_100_Year_Flood_Map_FAQs.pdf RELATED DATASETS Refer to the 100-Year Storm Flood Risk Zone shapefile for more information on the extent of the polygon https://data.sfgov.org/Public-Safety/100-Year-Storm-Flood-Risk-Zone-July-2022-/jzu3-4yxp/about_data.
