Excerpts from the news-gazette.com:

For fire departments, earning a Class 1 rating from the Insurance Services Office is the dream. The inspections are so rigorous that this year, just 305 of the more than 46,000 departments certified by the agency across the country earned that designation.

Only 16 of them are in Illinois — and Champaign County now has two, as the Urbana Fire Department has joined its sister agency across Wright Street in the exclusive Class 1 club.

In calculating its Public Protection Rating, the ISO looks at four factors: the fire department, the needed fire flow — the amount of water an engine needs to put out a fire — water supply and distribution, and emergency communications. So it’s not just the fire department that gets scrutinized but also METCAD and Illinois American Water.

The ISO grades communities on a 100-point scale, and anything above 90 earns a Class 1 rating. Urbana got a 90.92 this year, with the fire department scoring 42.02 out of 50, Illinois American Water scoring 36.65 out of 40 and METCAD scoring 9.55 out of 10.
