Ordinance No. 2245 Page 14 of 34 submit an acoustical analysis demonstrating that outdoor activity spaces associated with sensitive uses do not exceed 65 dB Ldn within these spaces. Implementation Measure 2 for MM 4.J-5c. Traffic Noise Exceedance Reduction Measure. MM 4.J-5c. shall be implemented as follows: the project shall include construction of a barrier along the north and east sides of the northeastern Level 4 rooftop deck. The barriers should run the length of the east and north edges of the rooftop deck, be at least approximately six feet high, have a minimum surface weight of approximately three pounds per square foot, and have no cracks or gaps. Glass or another transparent material can be used. With the barrier in place, traffic noise levels would be reduced to below 65 dBA Ldn at the northeast rooftop deck Level 4. MM 4.J-6a. For all of the potential sites for rezoning the City shall require site-specific acoustical assessments to determine noise exposure, impact, and mitigation regarding non- transportation sources. Noise exposure shall be mitigated to satisfy the applicable City Code criterion using appropriate housing site design. (Interior noise is to be addressed by MM 4.J- 5b. Exterior noise is to be addressed by MM 4.J-5c and its implementation measure.) MM 4.J-6c. For all of the potential sites for rezoning, the City shall require a noise disclosures and noise complaint procedures for new residents at the project site. The requirement shall include: a. A disclosure of potential noise sources in the project vicinity. b. Establish procedures and a contact phone number for a site manager the residents can call to address any noise complaints. MM 4.J-9. Prior to prior to PUD approval a potential site for rezoning would add traffic noise in exceed of 55 dBA described in Table 4.J-7, the project applicant shall conduct an off-site noise study to determine the project contribution to off-site roadway noise and contribute its fair-share to mitigate the established noise impact. Implementation Measure 1 for MM 4.J-9. Traffic Noise Increase Reduction Measure. MM 4.J-5a and MM4.J-9 shall be implemented as follows: the project applicant shall pay an amount equal to the project's percentage of traffic on each road segment anticipated to be affected by the project, multiplied by the incremental cost of using noise-attenuating pavement instead of regular pavement on that segment, to be paid prior to issuance of the first certificate of occupancy. If the cost amounts are not available at the time of project approval, the Community Development Director, or other City-designated official, shall identify that incremental cost prior to issuance of building permits. These fees will go to pay for the City to install noise-attenuating pavement, such as rubberized Hot-Mix Asphalt (R HMA), on the following eight impacted roadway segments. 1. Foothill Road north of Canyon Way (project's share is 1.65 percent) 2. Foothill Road south of Canyon Way (project's share is 0.81 percent) 3. Canyon Way east of Foothill Road (project's share is 2.16 percent) 4. Springdale Avenue north of Stoneridge Drive (project's share is 0.33 percent) 5. Springdale Avenue east of Springdale Avenue (project's share is 0.15 percent) 6. Stoneridge Mall Road north of Stoneridge Drive (project's share is 3.42 percent) 7. Stoneridge Drive east of Stoneridge Mall Road (project's share is 1.69 percent) 8. Stoneridge Drive west of Stoneridge Mall Road (project's share is 0.15 percent)
