The Toxic Tides map series shows the risk of flood exposure at hazardous facilities under a high greenhouse gas emission scenario (RCP8.5) in California in the years 2050 and 2100. Facilities included in these maps are those located in counties with low-lying land. A facility is considered at risk of flooding if a quarter of its elevation (25th percentile) falls below the water level. Flood risk estimates are averages of multiple simulations of future sea levels.

The Drinking Water Tool is an online resource for information about drinking water quality and access throughout California for community water systems and domestic well areas.

The Noise Pollution interactive map displays census tract level estimates of noise, categorized as below, slightly exceeding, and exceeding the U.S. EPA day-night average sound level (Ldn) limit of <55 decibels (dB). Points (census tract centroids) display values in the small-scale map and census tract boundaries appear when the user zooms in to a specific city. Available on the large-scale (zoomed in) map, users can click a specific census tract and see which noise category the tract falls into: (1) Ldn: low = <55 dB; medium = 55-58 dB; and high = 58+ dB; and (2) Median nighttime noise: low = < 40 dB; medium = 40-43 dB; and high = 43+ dB.
