Which super neighborhoods rank high on 311 flooding complaints, FEMA flood-insurance claims and Harvey high-water marks at the same time, and how socially vulnerable are they? Give me a profile of Gulfton compared with the city average — population, income, crime, fires, 311 complaints and flooding. Which neighborhoods flooded in three or more of the four big storms (Memorial Day 2015, Tax Day 2016, Harvey, Imelda)? Which neighborhoods have the most structural fires per km² and the longest average distance from each fire to its nearest fire station? Map the worst one with its fires and nearby stations. Which neighborhoods have the fewest cooling centers (city cool centers plus county library cooling sites) per 10,000 residents 65 and older? Which county air sensors logged the most hours above the unhealthy-for-sensitive-groups PM2.5 level in the past year, and which toxic-release facilities are within 3 km of each?
