6.2A Page 19 adoption by the SFPUC~ which can be implemented by the SFPUC. The mitigation measures proposed for adoption ill this section are the same as the mitigation measures identified in the Final EIR for the Project. The full text of the mitigation measures is contained in the Final EIR and in Attachment B, the Mitigation Monitoring and Reporting Program. The Commission finds that the impacts identified in this section would be reduced to a less-than-significant level through the mitigation measures contained in the Final EIR and set forth in Attachment B. This Commission recognizes that some of the mitigation measures are partially within the jurisdiction of other agencies, including the U.S. Fish and Wildlife Service, the California Department ofFish and Game, the Regional Water Quality Control Board, and the U.S. Army Corps of Engineers. The Commission urges these agencies to assist in implementing these mitigation measures, and finds that these agencies can and should participate in implementing these mitigation measures. Impact AES -2: Substantial new source of nighttime light during construction period. The Ravenswood tunnel shaft would be approximately 900 feet away from residential uses, and there are no other shielding land uses near the site. Current nighttime lighting levels at the adjacent East Palo Alto neighborhood are generally low, with street lighting and vehicular traffic on the Dumbarton Bridge producing much of that light. Therefore, nighttime lighting to light up an area of approximately 13.9 acres over the approximately four and a half to five years of construction would be a longer-tenn impact and would create a new source of substantial light affecting the adjacent residential uses during the construction period. Consequently, nighttime construction of the Project at this location would result in a significant impact on aesthetics. . Mitigation Measure AES-2: Construction Lighting Plan. Impact AES -3: Substantially contribute to permanent nighttime light pollution. New security lighting could create a substantial source of light adversely affecting adjacent land uses or contribute to permanent nighttime light pollution. Because lighting associated with operations would consist only of motion-sensitive lighting, any additional light generated in the Project area would be of short duration. However, depending on where the light is directed, it could create a substantial new source of light adversely affecting adjacent land uses or contribute to permanent nighttime light pollution. At the Hayward Fault East and West Valve Lots, for instance, where residences are located very close to the lots, it may not be possible to direct all nighttime lighting away from adjacent residences. Light from one or more small fixtures could be enough to result in annoyance and sleep disturbance for residents close to valve lots. This would be a significant impact. .
