Fairburn said the engineer did not adjust the cost for the piping going under the lake.
"Pipes going dry end to dry end is easier than going under the lake," he said.
The council also addressed the plague of wild animals roaming the streets of the city Monday night.
In a 9-0 vote, positions in animal control were restructured.
"We are creating a new position out of other positions," Fairburn said. "We are trying to get more hours onto the street for code enforcement."
Fairburn said in order for the city to match the needs of a seven day operation, the city needs to have two animal control officers.
"This will allow us to concentrate on the animal and the code side," he said.
The council will meet on again March 3 for a regular meeting and March 10 in a workshop session to discuss rezoning issues on Pondridge Road.
