SFEI is excited to announce the release of the SF Bay Shore Inventory: Mapping for Sea Level Rise. To provide a comprehensive and consistent picture of today’s Bay shore, SFEI mapped and inventoried Bay shore features that could affect flooding and flood routing for all nine Bay Area counties. While many different detailed levee layers exist, the region currently lacks a standardized regional dataset of elevated Bay shore features, accredited or not.

Mapping extends up to 10 feet above Mean Higher High Water and includes many shore features: engineered levees, berms, embankments, transportation structures, wetlands, natural shoreline, channel openings, and water control structures. Features were attributed with elevation, FEMA accreditation, how a structure was armored, whether a structure was fronted by a wetland or beach, ownership, and the entity responsible for maintenance, if known. The methodology was originally piloted in BCDC’s Adapting to Rising Tides (ART) project in Alameda and San Francisco counties. SFEI refined and extended the methodology to the whole Bay to complete a coherent and comprehensive dataset. 

The dataset is available in ESRI ArcGIS and Google Earth formats, and viewable online in SFEI's Resilience Atlas. For more information on the shoreline inventory dataset, please contact Jeremy Lowe.
