ADOT will share the results of field noise measurements with its project partners, including members of the public and key stakeholders. ADOT will make every reasonable effort to address concerns and be innovative and flexible within the federal and state regulatory framework for noise mitigation. Keep in mind that if the noise levels (expressed in LeqA1h) are at or above 64 dBA, it does not guarantee a noise wall will be constructed, as other factors must also be considered. ADOT will explore other possible innovative methods to reduce noise levels. Learn more about ADOT’s Noise Mitigation Policy at azdotgov/business/environmental-planning/noise. Chapter 6 of this policy provides information about the three reasonableness factors, or “tests,” that must collectively be achieved for a noise abatement measure to be deemed reasonable.
