DEP's modelled flood depths and ten years of 311 flooding reports, FloodNet's live street sensors, every catch basin and every right-of-way rain garden DEP has built — and which recurring hotspots have nothing built near them.

Sixteen years of the Community Air Survey: what each of the city's 42 neighborhoods breathed, what people report to DEP about it, and what DOHMH estimates that costs them.

The flood zones FEMA regulates New York under today, the 1% floodplains projected for the 2050s and 2080s, and the hurricane evacuation zones over them — click anywhere to see which reach it.

Every street DSNY's snow vehicles reached and when, storm by storm since 2016, against the salt they spread and what New Yorkers called 311 about.

Eleven seasons of DEP's harbor sampling — bacteria, oxygen and clarity at ninety-odd stations — against the combined sewer outfalls that discharge into the same water when it rains, and the beaches downstream of both.
