<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Adapting to Rising Tides program has developed this website to help Bay Area communities prepare for the impacts of current and future flooding due to sea level rise and storm surges by learning about causes of flooding, exploring maps of flood risk along our shoreline, and downloading the data for further analysis. These maps increase understanding of what could be at risk without future planning and adaptation, helping Bay communities, governments, and businesses to drive action. The Flood Explorer and associated flood maps are intended to be used as a planning guide to understand where our shoreline is at risk from current and future flooding from sea level rise and storms. The maps support adaptation planning by: Showing low points along the shoreline that can lead to inland flooding, enabling resources to be directed to areas that pose the greatest risk. Presenting flooding as a “Total Water Level” above mean higher high water (MHHW), which represents various combinations of storm-surge and sea level rise. In using this approach, the Flood Explorer communicates that some areas will be temporarily flooded before they are permanently inundated and therefore, supports development of early-, mid-, and long-, term thresholds for action. Providing high quality spatial information to support planning given that these high-resolution maps were carefully reviewed by local stakeholders. It is important to note that while the maps depict flooding that would result if water levels were higher, the shoreline is shown as it appears today. Thus, the maps represent flooding that would occur absent any preparatory action or shoreline changes. Additionally, users should note that while the maps represent areas that could be at risk of flooding in the absence of adaptation action, there are numerous adaptation planning efforts occurring at many scales all around the Bay Area. These maps are meant to help inform those efforts and reduce the risks associated with sea level rise. You can read more about mapping methodologies and analysis in the technical methods report.</SPAN></P></DIV></DIV></DIV>

Funding for the development of the ART Bay Shoreline Flood Explorer website comes from the California Air Resource Board, the Metropolitan Transportation Commission (MTC), and BCDC. This website was also prepared by BCDC using Federal funds under award NA16NOS4190123 from National Oceanic and Atmospheric Administration (NOAA), U.S. Department of Commerce. The statements, findings, conclusions, and recommendations are those of the author(s) and do not necessarily reflect the views of NOAA or the U.S. Department of Commerce. Website development was supported by the San Francisco Estuary Institute. The Flood Explorer hosts data developed through the Adapting to Rising Tides Bay Area Sea Level Rise Analysis and Mapping Project, which was funded by the Bay Area Toll Authority and MTC. AECOM, in collaboration with MTC and BCDC, created these sea level rise and shoreline analysis data for the entire Bay shoreline using methods and tools developed by BCDC, MTC, and partners in prior studies. As such, additional key contributors to these map products include: the Alameda County Flood Control and Water Conservation District, the San Francisco Public Utilities Commission, the California Department of Transportation – District Number 4, and San Francisco Estuary Institute. The project team also thanks DHI Group LLC., and the Federal Emergency Management Agency for the continued use and support of the maps developed for the San Francisco Bay Area Coastal Study. ART Bay Area analysis funding provided by a Caltrans Sustainable Transportation Planning Grant with additional funding by Metropolitan Transportation Commission (MTC), Bay Area Toll Authority (BATA) and Greenhouse Gas Reduction Fund (GGRF).

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The flooding maps and associated analyses provide a regional-scale illustration of coastal flooding due to specific sea level rise and storm surge scenarios, and are intended to improve sea level rise awareness and preparedness. The maps are not detailed to the parcel-scale and should not be used for navigation, permitting, regulation, project review, mitigation, actuarial estimations, or other legal uses. Flooding due to sea level rise and storm surges is possible in areas outside of those predicted in these maps, and the maps do not guarantee the safety of an individual or structure. While the maps use the best data available at its time of publication to capture topographic features (e.g., berms, tide gates), they may not capture other infrastructure improvements (e.g., pumps) designed to reduce future flood extent. The maps do not model flooding from other sources, such as riverine, groundwater, or surface water flooding from rainfall-runoff events, nor do they model erosion, subsidence, or local wind and wave effects.
