League City noise map: where the city is loudest

League City's 32 census tracts span the full range of the federal noise map. Of its 109,482 residents, 2.5% are exposed to 60 dB or more of average-day road, rail and aviation noise. Within that, 0.5% face the most severe band — 70 dB or louder, the level at which sustained exposure starts damaging hearing. A further 11.5% sit in the 45–60 dB band — a noticeable background hum rather than a hearing risk. Overall the city ranks #271 of 297, below the national median — quieter than most big US cities.

Among Texas's 37 cities of 100,000+ residents, League City is the 36th-loudest. Nationally it sits just below Oklahoma City, OK (#270) and just above Pueblo, CO (#272).

On the map, green tracts are the quietest and red tracts the loudest, with each colored by the share of its own residents above 60 dB — so you can see exactly which parts of League City carry the noise. The loudest tracts track the city's busiest road, rail and flight corridors. These are measured values from the US DOT's 2020 National Transportation Noise Map paired with Census population, aggregated to tracts by the University of Washington — real data per tract, no interpolation and no estimate.
