Evanston lost more than $11,000 as a result of the nine-day trash strike, city officials said Wednesday.

In a memo to City Manager Roger Crum, David Jennings, director of public works, wrote that the city spent an additional $11,264.87 during the strike by Teamsters locals 301 and 731.

Labor costs totaled $6,032.87, while disposal fees added up to $5,232.

City employees worked 280 hours cleaning up the city during the strike, Jennings wrote. The workers collected 100 tons of garbage more than they would normally collect.

The extra collection included pickups from condominiums, which are usually handled by private companies, Jennings wrote. Workers also picked up garbage bags on the ground near businesses and trash the city’s health department deemed hazardous.

Julie Cahillane, Northwestern’s manager of recycling and refuse, said she could not provide data on how much extra money the university spent during the strike.

“I’m not even sure how that would break down,” she said.
