Noise walls are typically considered for noise mitigation. In keeping with IDOT’s traffic noise assessment policy, any noise abatement measure must be determined both feasible (can it be constructed and will it achieve a specified traffic noise reduction level) and reasonable (a combination of noise reduction goals and a benefit-cost analysis) in order to be considered by IDOT for implementation. Where noise walls are found to be both reasonable and feasible, the public and immediate property owners will be notified. A public meeting or hearing will present the results of the traffic noise analysis and proposed abatement measures. The viewpoints on proposed noise walls will be solicited from residents who would benefit from the abatement, and the viewpoints determine if a noise wall will be constructed.
