An impact fee is a one-time payment levied onto a property developer by a local government meant to offset the new development's impact on public infrastructure. Impact fees frequently seen in Florida include water, wastewater, stormwater, roads, mobility, parks and recreation, public safety, library facilities, public art, public administration buildings and facilities, schools, inclusionary housing, and other in-lieu-of-fees. For many years, these impact fee programs – even ones based on poor methodologies—often went largely unchallenged in Florida.
