8.0 Exl�i�B� '� � ' 11 Noise and Vibration ' Impact 11-1. Exposure to Noise Levels Exceeding Standards. The accupants of new multifamily residential development within the DPP area could be exposed to noise levels in excess of City General Plan Noise Element land use/noise compatibility guidelines and State Title 24 standards. a) Potential Impact. The impact identified above is described and discussed on pages 11-17 to 11-20 of the DEIR. b) Mitigation Measures. FEIR Mitigation Measure 11-1 (p. 11-20 of the DEIR is hereb ado ted and will be im lemented as rovided in the Miti ation ) Y P P P � Monitoring and Reporting Program. c) Findings. Based on the FEIR and the entire record before the City, the City Council finds that Mitigation Measure 11-1 (pages 11-20 to 11-21 of the DEIR), will reduce this impact to a less than significant level because it will require that prior to the issuance of building permits for proposed new multifamily residential projects, noise studies consistent with the requirements of the California Building Code, and as approved by the City's Building Inspection Division, be conducted to identify noise reduction measures necessary to achieve compatibility with City Noise Element guidelines (55 dBA CNEL at sensitive exterior spaces) and Title 24 standards (45 dBA CNEL within residential units). Impact 11-2. DPP-Related Permanent Ground-Borne Vibration Impacts. Development under the proposed DPP would not be expected to introduce any permanent new sources of signif cant ground-borne vibration. However, the Draft DPP would permit new multifamiIy residential development within 100 feet of the Caltrain or California High-Speed Rail tracks. Ground-borne vibration levels are typically less than the FTA criteria for frequent events (72 VdB) at a distance of approximately 100 feet or more from the centerline of the nearest tracks. However, wheare new residential or other vibration sensitive uses are proposed within 100 feet or less of the nearest tracks, a potentially significant intermittent vibration impact could occur. a) Potential Impact. The impact identified above is described and discussed on pages 11-17 to 11-20 and 11-22 of the DEIR. b) Mitigation Measures. FEIR Mitigation Measure 11-2 (p. 11-23 of the DEIR) is hereby adopted and will be implemented as provided in the Mitigation Monitoring and Reporting Program. c) Findings. Based on the FEIR and the entire record before the City, the City Council finds that Mitigation Measure 11-2 (pages 11-23 of the DEIR), will reduce this impact to a less than significant level because it will require, as conditions of development approval, that detailed site-specific vibrations studies be conducted for proposed new habitable buildings within 100 feet of the Caltrain or California High Speed Rail right-of-way demonstrating that ground-borne vibrations either would not S\i2ESOLU'I IONS\Reso. 2092 CF.QA Findines for DPP Exhibit R.doc 40 012011
