The Littleton City Council voted by a narrow margin to raise fees 20 percent, or $30 a year, for sewer treatment plant users outside the city and zero percent for ones inside the city limits.
The decision will affect homeowners in areas of unincorporated South Jeffco despite the fact that they have no representation on the Littleton council.
The council also voted to raise tap fees for builders inside the city from $2,500 to $5,000 and outside the city from $2,828 to $5,656, except for projects that have site plans approved by Oct. 15.
