Program 9.2: Continue to require new development to pay its fair share to underground distribution facilities fronting the development and total costs within the development. [GP page 10-14] 11. NOISE ELEMENT Program 1.1: Use the normally acceptable designations and text description contained in Table 11-5, "Noise and Land-Use Compatibility Guidelines," to determine the acceptability of new development and to determine when noise studies are required. For new single-family residential development, maintain a maximum day/night average noise-level standard of 60 dBA L.dn for exterior noise in private or shared outdoor use areas excluding front yards. For new multi-family residential development, maintain a maximum standard of 65 dBA Ld„ in community outdoor recreation areas (or 60 dBA Ld„ when the outdoor noise is due to aircraft). Noise standards are not applied to balconies or front yards. In the Downtown, the City Council will evaluate the requirement to achieve these standards on a case-by- case basis. [GP page 11-24] Program 1.2: Where high noise levels are the result of railroad trains, an exterior noise level of up to 70 dBA Ld„ would be considered compatible with most residential development recognizing that day-night average noise levels are controlled by intermittent, loud events. Vibration-sensitive land uses located near the Union Pacific Railroad tracks should demonstrate compatibility with the Federal Transit Administration's vibration impact criteria by completing site-specific vibration analysis. [GP page 11-24] Program 3.1: Require new developments to pay their fair share of mitigation measures necessary to reduce interior noise levels within existing adjacent or impacted land uses. (GP page 11-25] Program 3.2: Require noise-attenuation measures when necessary to ensure that interior noise levels for new single- and multi-family residences do not exceed 45 dBA Ldf. Interior noise levels shall not exceed 45 dBA Ld„ in any new residential units (single- and multi-family). Development sites exposed to noise levels exceeding 60 dBA Ld„ shall be analyzed following protocols in Appendix Chapter 12, Section 1208, A, Sound Transmission Control, 2001 (current) California Building Code, Section 1207. [GP page 11-25] Program 3.3: New residential development affected by noise from railroad trains and aircraft shall be designed to limit typical maximum instantaneous noise levels to 50 dBA in bedrooms and 55 dBA in other rooms.
