In accordance with SB-200, the risk map is to be made available to the public and is to be updated annually starting January 1, 2021. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. </span><span style='font-size: 12pt; color: black;'></span></p><p style='background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;'><span style='font-size: 12pt; font-family: Avenir; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;'>This layer shows the combined hazard (water quality) and exposure (drinking water users) risk for all census block groups. The combined risk of each area is based on the water quality risk combined with the density of domestic wells and state small water systems. For each census block group, the combined risk is displayed as a percentile, with higher percentiles indicating higher combined risk. Additionally, the estimated count of domestic wells and state small water systems per census block group is displayed, along with the disadvantaged/severely disadvantaged status of each census block group based on median household income data from 2018.</span></p><p style='background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;'><span style='font-family: "Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size: 16px;'>Methodology for the draft aquifer risk map </span><a href='https://gispublic.waterboards.ca.gov/portal/home/item.html?id=6a50a6cd22a144e9ac621e9070e01c44' rel='nofollow ugc' style='color: rgb(0, 121, 193); text-decoration-line: none; font-family: "Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size: 16px;' target='_blank'>available for download</a><span style='font-family: "Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size: 16px;'>.</span></p> |
