~. • Require exterior to interior noise reduction measures to reduce interior noise levels Auto Mall and Retail Center Require exterior to interior noise reduction techniques to reduce interior noise levels Limit exterior noise levels from the auto mall car wash stations, including vacuuming areas, to 60 dBA at any habitable structure on the CLC property Community Park Limit areas within the 65 CNEL contour to primarily open space (with limited trails) and place active park uses such as playgrounds outside of the contour Stoneridge Drive (by Proposed Bridge) • Provide noise attenuating pavement to new portions of Stoneridge Drive (by the proposed bridge) Recommended mitigations require pile driving vibration to be less than the structural damage threshold. Early public notices about bridge construction dates are required, as well as a posted sign stating the construction date on site. A noise disturbance coordinator would be appointed who would be responsible for handling complaints about noise during construction. Recommended traffic mitigations include requiring the payment of the City's existing Traffic Development Fee or the fee update which is anticipated to be completed prior to the payment of fees by this project. The improvements (e.g., new turn lanes, through lanes, changing cycle length, narrowing lanes to reduce pedestrian crossing times) would reduce the project's impacts to less than significant levels. The Hopyard/Stoneridge signal would need to be retimed by the City. Per the 2007 Cost Sharing Agreement between the cities of Pleasanton and Livermore and the ACSPA, the City of Livermore is obligated to address impacts at the EI Charro Road/I-580 off ramp. The agreement also provides that if this intersection is not improved by Livermore then the City of Pleasanton will make the improvements. The funding of the improvements required for the intersection of Stoneridge Drive/EI Charm Road (in the cumulative scenario) will be included in the overall funding plan for the extension of Stoneridge Drive which would be developed by the City of Pleasanton at a future date. If that funding has not occurred when building permits are issued, the City will be responsible for making these improvements. • The recommended mitigation measures require each developer to provide a construction access plan which minimizes the use of Stoneridge Drive as a construction route. Measures such as notification procedures for adjacent property owners regarding when major deliveries and lane closures would occur would also be required.
