activities. The duration of pile driving activities depends on a number of factors including building design and location, as well as depth to bedrock. It can reasonably be expected that a substantial multi-story structure may require multiple weeks of pile driving during which peak noise levels will exceed 90 dBA.

[See page 5-248 for the original comment] Typical noise levels from pile driving were presented in Table 4.J-7 of the Draft EIR. Standard construction equipment (i.e., equipment other than pile drivers) would generate the noise levels shown in Table 4.J-8.

[See page 5-248 for the original comment] Mitigation Measure 4.J-4b is presented on Draft EIR page 4.J-35. The first paragraph of page 4.J-34 is revised to read as follows:

To ensure that construction noise is minimized under construction of Project Site development, Mitigation Measure 4.J-5b 4.J-4b below is recommended.

BCC-453

[See page 5-249 for the original comment] The intent of the mid-day restriction on pile driving discussed in Mitigation Measure 4.J-4a of the Draft EIR is to accommodate a relief from pile driving noise during a typical lunch hour. The mitigation measure would permit pile driving and/or other extreme noise-generating activities (greater than 90 dBA) between 8:00 a.m. and 12:30 p.m. and between 1:30 p.m. and 4:00 p.m. Monday through Friday.

[See page 5-249 for the original comment] The following table is added as a text amendment after the first paragraph of Draft EIR page 4.J-36 to read as follows:

BCC-455

[See page 5-249 for the original comment] Long-term construction activities under development plans typically occur in isolated phases as discussed in Section 3.14 of the Draft EIR. The first phase of development would occur on the former railyard portion of the Baylands Project Site and would proceed eastward from there. These structures constructed in earlier phases would provide some
