Migrating birds such as songbirds can be affected by human-built structures because of their propensity to migrate at night, their low flight altitudes, and their tendency to be disoriented by artificial light, making them vulnerable to collision with obstructions. Both tall structures such as wind turbines and windows on buildings provide collision hazards to migrating birds. A majority of bird strikes occur when birds do not recognize windows on buildings. Thus, operation of the wind turbines and tall residential (DSP and DSP-V scenarios) and non-residential buildings would pose collision hazards to migratory birds since effects associated with the lighting of the towers can alter the flight patterns of migratory birds and substantially increase bird strike collisions with the structures. As discussed in

Section 4.C, Biological Resources, of this EIR, due to the potential for bird strikes at tall buildings associated with construction of dense urban development with many windows adjacent to the Bay and within the Pacific Flyway, an increase in bird strikes would occur. Mitigation measures are set forth in Section 4.C, Biological Resources, would to reduce impacts related to bird strikes tall structures and increased night lighting. The following measures would reduce bird strike impacts to below a level of significance less-than-significant levels by incorporating design features that would help minimize bird strikes, including design features making structures, especially glass surfaces, more visible from the outside.

• Mitigation Measure 4.C-4d to minimize the effects of a building’s lighting on birds.
• Mitigation Measure 4.C-4e addressing the external appearance of buildings to minimize the risk of bird strikes. Such measures, which may include the following and/or other measures, shall be incorporated into the building’s design:

These measures require the City to ensure that building design related measures to reduce the risk of bird collisions have been incorporated to the extent practicable.

Page 4.A-40    OSEC-66 [See page 5-311 for the original comment] REVISE Mitigation Measure 4.A-4a to read as follows:

Mitigation Measure 4.A-4a: All development within the Project Site shall comply with the following lighting design standards in order to minimize project lighting to the extent required for safety and comfort only in order to reduce nighttime lighting effects:

• Exterior lighting shall be kept to the minimum required for safety; purely decorative lighting displays shall be prohibited.
