Section 8: Noise/Sound Walls
Ensure compliance with commitments made for the project regarding noise abatement. If necessary, do the following as required in the contract:
- Anchor: #DIMJCVWN
- Become aware of the commitments pertaining to noise abatement as proposed in the traffic noise analysis report and as implemented in the PS&E. Anchor: #JPSHXQPC
- Ensure the noise/sound walls required by commitments are installed to provide mitigation to adjacent impacted noise-sensitive receptors. Anchor: #IVGFBJUF
- Ensure that district environmental staff and ENV are notified and/or given an opportunity to review change orders that affect noise abatement included in the PS&E. ENV submits inventory information on constructed noise barriers to FHWA every three years and needs accurate information about changes.
If phasing or timing regarding noise/sound walls are not specified in the general notes or traffic control plan of the PS&E, contractors are encouraged to schedule and perform work related to noise/sound walls early during construction. This provides mitigation for noise impacts to communities adjacent to the project.
