Understanding Traffic Noise

Unfortunately, noise barrier walls are only considered if a receptor meets all federal and state criteria (predicted noise levels approach, meet, or exceed the NAC) and the noise barrier wall is determined to be feasible and reasonable. FDOT cannot add a noise barrier wall outside of this process or as a result of petitions or individual requests. Any noise barrier wall that meets all criteria are presented to the public, and the viewpoint of affected property owners and residences is solicited to confirm community support of the proposed noise barrier wall.

FDOT’s Traffic Noise Policy follows federal regulations established by the Federal Highway Administration (FHWA) and applies to Type I projects—which are roadway improvements that could increase traffic noise. Examples of these projects include widening highways by adding through lanes, building new roadways or interchanges, or significantly changing the road’s horizontal or vertical alignment. If your property is near a project classified as a Type I project and is considered noise sensitive (such as a residence, school, or park), it will be evaluated as part of the noise study. The study will determine if traffic noise impacts will occur, and if noise abatement (noise barrier walls) is warranted, feasible, and cost reasonable under federal and state criteria.
