A task force formed to look at City Hall control over growth and its costs soon will conduct hearings to see how ideas play with developers and the public.

“We’ll go out and do some meetings, get some feedback from people,” City Commissioner David Dunfield said during Tuesday’s meeting of the Public Improvements Task Force.

The task force is considering new taxes, impact fees and other financial tools to pay for parks, streets, extended fire protection and other services that must expand when the city grows.

The idea is to help City Hall guide where and how Lawrence will grow and to shift the costs of expanded services to new developments and away from the rest of the community’s taxpayers.

County Commissioner Bob Johnson, a task force member, said Tuesday that developers already pay much of the costs of growth: streets, sewers and sidewalks that are so new the city won’t have to pay maintenance costs for years.

“When does the cost of growth cease to be the cost of growth and become part of the cost of the city?” he asked.

Dunfield said after the meeting that the city still absorbed some growth costs — and always would. The question, he said, is how to divide costs between developers and the city.

The price tag on the recommended fees and charges won’t be known until City Hall determines how much it spends on growth.

After public hearings, the task force will make recommendations to the City Commission.

But the public hearings have not yet been scheduled. That could happen at the task force’s next meeting, 8 a.m. April 27 in City Hall, Sixth and Massachusetts streets.
