[See page 5-247 for the original comment] Mitigation Measure 4.J-2b on Draft EIR page 4.J-25 is revised to read as follows:
Mitigation Measure 4.J-2b: Pre-Construction Assessment to Minimize Structural Pile-Driving Vibration Impacts on Adjacent Historic Buildings and Structures and Vibration Monitoring. Any development within 85 feet of the Roundhouse and the Machinery & Equipment Building that would require pile driving or other construction techniques that could result in vibrations of 0.25 in/sec shall engage a qualified geotechnical engineer subject to City approval to conduct a pre-construction assessment of existing subsurface conditions and the structural integrity of the nearby historic structures subject to pile-driving or other vibration-inducing activity before a building permit is issued to demonstrate that the proposed construction activities would not result in vibration-induced damage to the Roundhouse building or the Machinery & Equipment Building.
[See page 5-247 for the original comment] Methods to achieve the performance standards identified are described in the U.S. Department of Transportation’s document Transit Noise and Vibration Impact Assessment. The effectiveness of wave barriers has been documented in the paper Field Experiments on Wave Propagation and Vibration Isolation by Using Wave Barriers (Firat et.al., 2010)
