What will be done to mitigate the noise of the new busy road where it passes near houses?
No noise abatement measures are being recommended as part of this project. While the environmental document originally identified noise mitigation for the Shelly Woods Subdivision, this recommendation was based upon conceptual engineering information. During the design phase of the project, the noise analysis was reevaluated utilizing more detailed information and the most recent version of the FHWA noise model to determine if the preliminary recommendations were still valid. As a result of this reevaluation, it was determined that noise abatement would not be reasonable. The noise analysis process starts with the DOT&PF identifying noise impacts. In accordance with federal guidance, an impact exists when traffic noise approaches or exceeds the FHWA noise abatement criteria (NAC); or results in a substantial increase in predicted noise levels. DOT&PF’s Noise Policy defines “approach” as within 2 dBA of the NAC (for residential land uses the NAC is 67 dBA, so DOT&PF policy defines a noi
