For the past week, Tappan Zee Constructors, LLC (TZC) has been installing and testing extensive noise mitigation measures in an effort to mitigate noise from vibratory sheet pile driving at Pier 1 off the Rockland shoreline. These efforts have successfully reduced the noise levels by more than 10 decibels. This work is expected to last 1-2 weeks with limited work hours and no sheet pile driving at Pier 1 on Saturdays, Sundays or Memorial Day Monday.
To minimize the effect on the local community, TZC will:
- Limit the sheet pile driving at Pier 1 to the hours of 8AM-4PM Monday-Friday (none allowed on Saturday, Sunday or Memorial Day Monday )
- Drive no longer than 30 minutes per hour
- Use a noise shroud over the vibratory hammer
- Erect a 40-ft wide x 30-ft tall temporary noise barrier between the work and South Nyack residents
- Place noise barrier material over the previously driven sheets to reduce noise/vibration levels
- Proactively reach out to the Village of South Nyack and local homeowners to inform them of the mitigation measures
Noise levels at sensitive receptors and nearby homes are expected to remain within the allowable levels listed in the New NY Bridge project’s Final Environmental Impact Statement as shown in the table below:
