BROOKLYN LEVEL UPThe Flats · East Flatbush, Brooklyn
BLOCK CHECKCOMMUNITY TOOL · SAMPLE DATA
THE DATA ON YOUR BLOCK ALREADY EXISTS.
The city measures heat, air and flooding street by street — then buries it in maps and reports nobody has time to read. This tool says it plain: what's happening where you live, and what you can do with it.
START HERE
CHECK YOUR BLOCK
Type your street, corner or ZIP in The Flats. Heat and air readings come back live from current conditions at your coordinates. Rain is a three-day forecast. The block-level city layers are named below — those aren't connected yet.

Add a block, corner or ZIP so the reading matches where you actually live.

What these numbers are: heat and air are live measurements for your coordinates,
right now. Rain is a three-day forecast. All three come from Open-Meteo, which models
conditions on a grid of roughly one to eleven kilometers — close to your block, but not
your block. Two houses on the same street will return the same reading.

WHAT WOULD MAKE THIS BLOCK-LEVEL
Live weather tells you what today is doing. It can't tell you why this block runs hotter than the one six streets over, or which corner floods first. That takes city data collected block by block. These three sources exist and are public — they just aren't wired in yet.
HEAT
HEAT VULNERABILITY INDEX
NYC Health Department. Scores every neighborhood on tree canopy, surface temperature, air conditioning access and more. This is the layer that explains why a heat wave lands harder here.
AIR
NYC COMMUNITY AIR SURVEY
NYCCAS runs real monitors at street level across the city. Live forecast air quality is modeled; NYCCAS is measured, and it captures the traffic corridors that a regional model smooths over.
WATER
STORMWATER FLOOD MAPS
NYC DEP maps which streets pond and back up in a heavy rain. Rainfall alone isn't flood risk — where the water goes depends on drainage, grading and pavement. This is the missing half.
WHAT THE DATA DOESN'T KNOW
ADD WHAT YOU KNOW
No public dataset knows whether your AC works, or which corner goes under first. You do. Four questions, about thirty seconds.
Before you answer — what this records.
Your answers below, and the conditions at the moment you sent them.
A rounded location, accurate to about a block. Not your address.
What it does not record.
No name, no phone, no email, no apartment number.
Not the address you typed in above — that stays in your browser.
This is not a way to report an emergency or request a repair. For an emergency call 911. For a city service or a repair complaint, call 311.
GOT IT.
Building AC access and street-level flooding aren't in any public dataset. Enough of these from enough neighbors is the thing an agency can't wave off.

WHAT TO DO WITH IT
YOUR NEXT MOVE
ONE BLOCK IS A DATA POINT. A CORRIDOR IS AN ARGUMENT.
A reading on its own tells you how to get through the week. Enough readings from enough neighbors become something an agency has to answer for. Bring yours to the table.
