Noise and Vibration (cont.)

These noise levels shall be attained through use of appropriate building materials as required by state of California Title 24 standards. Compliance with these performance standards shall be verified by an acoustical professional prior to issuance of a building permit. Specific measures to achieve these performance standards shall include all or any combination of the following options:

• Site design measures, including use of building orientation to minimize window exposure toward noise sources, avoid placing balcony areas in high noise areas, and use of buildings as noise barriers.
• Use of acoustically rated building materials (insulation and windows);
• Construction of architectural noise barriers between sources and receptors; and
• Provision of landscaping or other non-noise-sensitive buffer zones between sources and receptors.

The City Building Official shall also be responsible for monitoring site construction to ensure that the development features proposed by the applicant to meet applicable performance standards are constructed as approved.

Mitigation Measure 4.J-1b: All hotel projects within the Project Site shall minimize the exposure of people within the Project Site to noise from Caltrain operations through construction of noise barriers or maintenance of buffer distances, and shall adhere to the following noise performance standards:

• Exterior noise level of below 65 dBA, DNL for outdoor common areas within any approved residential use or hotel; and
• Interior noise standard of 45 dBA, DNL

These noise levels shall be attained through use of appropriate building materials as required by state of California Title 24 standards. Compliance with these performance standards shall be verified by an acoustical professional prior to issuance of a building permit. Specific measures to achieve these performance standards shall include all or any combination of the following options:

Applicant(s) for hotel development shall provide a noise analysis prepared by an acoustical professional verifying that the performance standards set forth in Mitigation Measure 4.J-1a will be achieved.
