108" Inundation Vulnerability Zone Line (Sea Level Rise + 100YR Flood Event)

Disclaimer: The Sea Level Rise (SLR) map shows the most extreme level of SLR possible. It is a very, very unlikely scenario that would only occur if no efforts to address SLR occur and both a King Tide and 100-year storm occur at the same time. The real purpose of the maps is to provide a broad net to help the City identify projects that that may be vulnerable. The data is based on what was in the ground as of 2010 and doesn’t include piers.

The inundation maps and the associated analyses are intended as planning level tools to illustrate the potential for inundation and coastal flooding under a variety of future sea level rise and storm surge scenarios. The maps depict possible future inundation that could occur if nothing is done to adapt or prepare for sea level rise over the next century. The maps do not represent the exact location or depth of flooding. The maps relied on a 1-m digital elevation model created from LiDAR data collected in 2010 and 2011. Although care was taken to capture all relevant topographic features and coastal structures that may impact coastal inundation, it is possible that structures narrower than the 1-m horizontal map scale may not be fully represented. The maps are based on model outputs and do not account for all of the complex and dynamic San Francisco Bay processes or future conditions such as erosion, subsidence, future construction or shoreline protection upgrades, or other changes to San Francisco Bay or the region that may occur in response to sea level rise. For more context about the maps and analyses, including a description of the data and methods used, please see the Climate Stressors and Impacts Report: Bayside Sea Level Rise Inundation Mapping Technical Memorandum, July 2014.

免责声明：本海平面上升（SLR）图展示了可能发生的最极端海平面上升水平。这种情况发生的可能性极低，仅在没有采取措施应对海平面上升的情况下，同时发生王潮和百年一遇的风暴时才会出现。地图的真正目的是为城市提供一个广泛的网络，以帮助识别可能面临风险的项目。数据基于2010年地面状况，不包括码头。

洪水图及其相关分析旨在作为规划工具，以展示在多种未来海平面上升和风暴潮情景下可能发生的洪水和海岸洪水。地图描绘了在接下来的一个世纪内，如果不采取适应或准备措施应对海平面上升，可能发生的未来洪水情况。地图不表示洪水的确切位置或深度。地图基于2010年和2011年收集的激光雷达数据制作的1米数字高程模型。尽管已尽力捕捉所有可能影响海岸洪水的影响地形特征和海岸结构，但仍有可能宽度小于1米水平地图比例尺的结构无法完全体现。地图基于模型输出，并未考虑所有复杂且动态的旧金山湾过程或未来条件，如侵蚀、沉降、未来的建设或海岸防护升级，或对海平面上升可能发生的旧金山湾或该地区的其他变化。有关地图和分析的更多背景信息，包括数据和方法描述，请参阅《气候压力源和影响报告》：2014年7月《旧金山湾海平面上升洪水图技术备忘录》。
