Central Valley city to use flags to signal air pollution
March 25, 2008
• Color-coded banners will flutter atop city buildings
• Idea started with local schools
How bad is the air pollution? If you’re in Merced, just look at the flags.
In the Internet era, in a city served by multiple radio and television stations and a daily newspaper, Merced is turning to colored flags to alert residents about air quality.
A green flag would signal that air quality is good enough to be outside. An orange flag would be a caution that those with respiratory concerns should avoid outside activities.
It’s an extension of an idea first tried by the city’s schools in 2004.
The city’s banners are being paid for by the Merced/Mariposa Asthma Coalition.
