This map is Priority Zone 1, as presented in the County’s updated "Countywide Risk Assessment and Resilience Plan" reflective of modeled flood elevations, satellite-based temperature data (LANDSAT8 from NASA) and household income (ACS) data. Weighted ranks of census tracks for percentage of low to moderate income households (50% weight), flood water volume (33% weight), and maximum surface temperature (17% weight) were used to create this map. This map establishes socio-economically vulnerable geographic areas for priority investment in heat and flood mitigation strategies.本地图为优先1区，源自该县更新发布的《全县风险评估与韧性规划》，其编制依据包含模拟洪水高程数据、美国国家航空航天局（NASA）LANDSAT8卫星遥感温度数据，以及美国社区调查（ACS）的家庭收入数据。本次制图通过对人口普查区块的三项指标进行加权排名：中低收入家庭占比（权重50%）、洪水水量（权重33%）以及地表最高温度（权重17%）。本地图划定了社会经济脆弱的地理区域，用于开展高温与洪水减灾策略的优先投资布局。
