The Audubon City Council met Monday evening.  Audubon City Clerk Lora Hansen tells KJAN news the council voted 4 to 1 to increase sewer rates in the city by 15 percent.  The Council will discuss at a later date when that rate increase might go into effect.  The Audubon City Council also voted Monday not to raise the salaries of city employees.  Any increase in salaries will likely not be brought up again until next May or June.
