Although much attention has focused recently on the adoption of impact fee assessments, the tasks required to implement an impact fee system successfully receive little emphasis. With ten years experience in administering impact fee assessments, Broward County, Florida has accumulated valuable insights into the implementation process. Based on the Broward County experience, I outline some of the major concerns that staff should address in designing an impact fee system. I emphasize coordinating components of local staff work and facilitating the spending of the revenues.
