Flnding: Impleme�tation of Mitigation 13-3 would reduce this potential intermittent and short-t�rm project vibration impact to a less-than-sign�ca�t level. Facts in Suppart of Finding: Implementatian of Mitigation 13-3 would reduce project- facilitated grvundbome demolition and construction vibrakior� le�els to a less- than-sign�cant le�el by res#ncting vibration-generating acti�ity and app�y�ng quantitati�e performance standards. These facts are described and quar�tified in Draft EIR chapter �3 (Noisey on pages 13-1 through 43-20, w�ich is hereby incorporated by reference. Impact: Impact 13�: Potential Noise from Parking Structure Ventilation System. Noise generated solely by the ventilation system and otl�er mechanical eq�ipment for the potentia� parking structure at the corner of Bay lRoad and Barron A�enue cauld substantially exceed existing ambient levels at residences in the area or the Redwoad City Noise Guidelines far Land Use Planning (see Draft EIR Tabl� 13.4) because the parking structure would be lacated proximate to residences on 2"d A�enue. Mitigation: Mitigation 73-4. During the project detailed design phase for the potential parking structure at the comer of Bay Road and Barron Avenue, the project applicant shall submit an aooust3cal study to demonstrate haw the parking structure design would meet the fol�owing noise standards at the most affected receiv�r: fi0 dBA CNE� and 60 dBA L�_h�daytime (7:00 AM to 7:00 PM}, 55 dBA L�,_nr evening {7:00 PM to 10:00 PM), �nd 50 dBA Ley�nr nighttime (10:04 PM to 7:00 AM). The design rrEeas�res may include, for example, the instalfation of silencers and baffles as neoessary to reduce the noise le�el at the nearest resider�tiai praperty line to the existing ambient noise level. Finding: Implementation of Mitigation 13-4 to fhe satisfaction of the Redwood City Community Development Department woufd reduce this �entilatian naise impact to a less-than-sign�cant level. Facts in Support of Finding: ImplementatioR of Mitigatian 13-4 would reduce noise from the parking structure ►►entilativn system prapased for the corner of Bay Road and Barron Avenue, w#�ich is near residences on 2"d Avenue, to a less-thar�- significant le�el. The mitigation defines maximum allowable decibel le�els {performance sfar�dards), which are typically met through standard ventilatian design measures such as silencers and baffles. These facts are described and guantified in Draft EIR chapter 13 (Naise) on pages 13-1 through 13-20, w�ich is hereby incorporated by reference. Transportation, Circulation, and Parkins� Impact: Impact 7-1: Existing Plus Project Impact on Woodside RoadlBroadway Inters�ction. Under Existing Plus Project conditio�s during the PM peak hour, praject tra�c would cause the intersectian to degrade from LOS � (59.3 seconds delay}to LOS F (128.8 seconds delay).
