shall be submitted to the City for review and consultation with affected utilities a minimum of two weeks prior to commencement of construction activities. If underground utilities are identified within 15 feet of proposed pile driving activities, alternative pile installation methods shall be required. Alternative methods may include use of sonic drivers or drilled and cast-in-place piles. All pile driving shall be designed so as to result in peak particle velocity of less than 4.0 in/sec (100 mm/s) at the location of underground utilities.
Within one week following completion of pile driving activities, a post-construction assessment of all underground utilities within 30 feet of the pile driving activity shall be submitted to the City by the contractor, confirming that no damage to any underground utilities occurred as the result of the pile driving activity. Should the post-construction assessment determine that underground utilities were damaged by pile driving activities, such damage shall be repaired by the contractor to the satisfaction of the City and affected utility.
In addition, the first full paragraph on page 4.J-26 is hereby revised to read:
Conclusion with Mitigation: With implementation of Mitigation Measures 4.J-2a,
and4.J-2b, and 4.J-2c, groundborne vibration impacts on multi-family housing under the DSP and DSP-V scenarios, and on the Roundhouse and underground utilities and pipelines for Project Site development would be less than significant.
[See page 5-360 for the original comment] The Draft EIR statement on page 5-26 cited in this comment makes no value judgment as to whether the amount of onsite population under the No Project – General Plan Buildout Alternative is beneficial or detrimental. The cited statement notes only that the reduced amount of development within the Baylands under that alternative would not likely meet one of Project Site development’s objectives – supporting a robust expansion of transit.
[See page 5-360 for the original comment] A “fixed axis” PV system is one whose photovoltaic panels are constructed at a stationary angle and do not move during the day. A “single axis” tracking PV system is one whose photovoltaic panels are constructed so as to turn along a single axis during the day to maximize capture of sunlight.
[See page 5-360 for the original comment] The reasoning behind the identification of the environmentally superior alternative is set forth in Draft EIR Section 5.4. As stated on page 5-66, the No Project-No Build Alternative “would not be environmentally superior since it allows existing site contamination to continue without remediation.”
