Greater Grand Crossing noise map: how loud is it?

Greater Grand Crossing is home to about 29,473 residents across 32 census tracts. 14.4% of them are exposed to 60 dB or more of average-day road, rail and aviation noise. Within that, 4.2% face the most severe band — 70 dB or louder, the level at which sustained exposure starts to threaten hearing. A further 85.6% sit in the 45–60 dB band — a noticeable background hum rather than a hearing risk. That ranks Greater Grand Crossing #18 of 77 Chicago neighborhoods, louder than most Chicago neighborhoods. Among Chicago neighborhoods it sits just below Roseland (#17) and just above West Garfield Park (#19).

Exposure across Greater Grand Crossing is a patchwork. The streets that back onto a freeway, rail line or flight path carry most of the 14.4%, while interior blocks a few hundred feet away can sit 15 to 25 dB quieter. The map makes that split easy to see.
