Environmental Checklist and City of Pleasanton–10x Genomics Project Environmental Evaluation Initial Study/Mitigated Negative Declaration 142 FirstCarbon Solutions Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480024/ISMND/wp/21480024 10x Genomics Project Full Screencheck ISMND.docx and present development within the Air Basin; however, the proposed project’s contribution would only be an incremental increase from the prior land use. MM AIR-1 would require implementation of BMPs recommended by the BAAQMD to reduce fugitive dust emissions. Additionally, Section 2.3, Air Quality, provided an analysis of cumulative health risks and determined that cumulative health risk impacts would be less than the BAAQMD’s cumulative thresholds of significance after implementation of MM AIR-2. Implementation of MM AIR-2 would require minimization of impacts to sensitive receptors during construction activities and would reduce health risk impacts of the proposed project. With implementation of MM AIR-1 and MM AIR-2, the proposed project would not result in any potentially significant and unavoidable cumulative impacts related to air quality. Section 2.13, Noise, determined that impacts related to operational and mobile source noise under cumulative conditions would be less than significant, and that no mitigation measures are needed. The proposed project would not result in any potentially significant and unavoidable cumulative impacts to noise. Section 2.17, Transportation, included an analysis of impacts related to cumulative conditions with project traffic. According to the Transportation analysis, the addition of project traffic is anticipated to contribute to excessive vehicle queue spillback on Springdale Avenue (southbound) between Stoneridge Drive and the project driveway entrance, Stoneridge Drive (eastbound left turn lane) at Springdale Avenue and Stoneridge Drive (eastbound) between Stoneridge Mall Road and Springdale Avenue. Implementation of MM TRANS-1 and MM TRANS-2 would reduce impacts related to queueing under the cumulative traffic condition. Therefore, cumulative transportation impacts would be less than significant with mitigation. Implementation of MM AIR-1, MM AIR-2, MM BIO-1, MM BIO-2, MM CUL-1, MM CUL-2, MM TRANS-1, and MM TRANS-2 would reduce the proposed project’s cumulative impacts to less than significant. No additional mitigation measures would be required to reduce cumulative impacts. Therefore, with implementation of the specified mitigation measures, the proposed project would cause less than significant cumulative impacts. c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directly or indirectly? Less than significant impact with mitigation incorporated. Based on the discussion provided in the Project Description and the analysis presented in Sections 2.1 through 2.19 of this Draft IS/MND, the proposed project would not cause substantial adverse effects on human beings, either directly or indirectly, because the project’s potential impacts would be mitigated to a less than significant level. Therefore, with implementation of MM AIR-1, MM AIR-2, MM BIO-1, MM BIO-2, MM CUL-1, MM CUL-2, MM GEO-1, MM GEO-2, MM GHG-1, MM HAZ-1, MM HAZ-2, MM NOI-1, MM TRANS-1, MM TRANS-2, MM TRANS-3, and MM TRANS-4 the proposed project would not result in substantial adverse effects on human beings. Impacts would be less than significant with mitigation incorporated.
