Pile Driving Noise Study


2018 Pile Driving Report


The Noise Office first learned about noise impacts from pile driving in 2014, when a group of

Pearl District residents began contacting the Noise Office about how they were impacted by

pile driving construction. Since then, the Noise Office has spent over 400 hours of staff

time to examine the issue in more detail including:


  • • Conducting research

  • • Holding meetings

  • • Investigating complaints

  • • Hearing testimony

  • • Interacting with residents, contractors, developers, and union tradespeople

  • • Participating in the Noise Task Force convened by Commissioner Fritz


Through research and discussions with construction and geotechnical professionals, the Noise Office found no current engineered solutions, acoustic damping accessories or safe noise mitigation applications that were tested and ready to be incorporated into City Code or into the process of noise variance reviews by staff and the Noise Review Board. In addition, the Noise Office found no significant differences from the 2015 findings.
