Its conclusions regarding the noise potentially resulting development of those sites plus General Plan buildout (the cumulative scenario studied in that SEIR) are set forth in Table 4.J-7 of the SEIR. Tables 4.J-6 and 4.J-7 are provided in the Attachments. The Mitigation Monitoring and Reporting Program (MMRP) adopted by the City based upon the SEIR includes the following mitigation measures: Mitigation Measure 4.J-5a: Prior to PUD approval, if a potential site for rezoning would add traffic noise in excess of 55 dBA as described in Table 4.J-6, the project applicant shall conduct an off-site noise study to determine the project's contribution to off-site roadway noise and contribute its fair-share to mitigate the established noise impact. Mitigation Measure 4.J-9: Prior to PUD approval, if a potential site for rezoning would add traffic noise in excess of 55 dBA as described in Table 4.J-7, the project applicant shall conduct an off-site noise study to determine the project’s contribution to off-site roadway noise and contribute its fair-share to mitigate the established noise impact. This memorandum describes how the Project will satisfy these mitigation measures, by determining its contribution toward the total traffic projected to use the relevant road segments identified in Tables 4.J-6 and 4.J-7. C.METHODOLOGY Study Roadway Segments Nearby roadways were selected as the Project’s study area to determine the Project’s fair share contribution, while the remaining impacted roadways referenced in Tables 4.J-6 and 4.J-7 were not evaluated since Project traffic is not assumed to be added to these roadways. The 10X Genomics Final Transportation Impact Analysis (TIA)2,was used as the basis for determining the roadway segments that would be materially affected by the Project, as the 10X Geonomics study addresses a project across the street from the Project and was recently approved by the City. The 10X Genomics TIA conducted an intersection level of service (LOS) analysis at select intersections. Therefore, roadway segments were determined as the roadways between the study intersections. To determine whether additional roadway segments beyond what was considered in the 10X Genomics TIA, a trip generation comparison was conducted between the Project and 10X Genomics. If the Project generates fewer trips than 10X Genomics, the 10X Genomics’ study area would be considered sufficient for this analysis and roadway segments outside of the 10X Genomics’ study area were not evaluated since the Project would not add trips to these segments. A comparison of the daily, AM peak hour, and PM peak hour trip generation for the Project and 10X Genomics is shown in Table 1. Trip generation was determined for the Project using the most recent 2 10X Genomics Final Transportation Impact Analysis,Fehr & Peers, March 2021.
