City of Pleasanton—Stoneridge Mall Residential Project CEQA Checklist Section 15183 Checklist/15164 Addendum 186 FirstCarbon Solutions Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480017/Consistency Checklist/21480017 Stoneridge Mall Residential Project Checklist Addendum_Updated.docx the Prior EIR and is identified throughout this document, the proposed project would not have the potential to significantly degrade historic resources. Therefore, there are no impacts that are peculiar to the proposed project or the parcels on which the proposed project would be located. Impacts would be less than significant and the proposed project would not result in a new or more severe adverse impact that was not previously identified in the Prior EIR. b) Cumulatively Considerable Impacts Prior EIR Conclusions The Prior EIR found that buildout of the Housing Element would have cumulatively considerable and unavoidable impacts to traffic. While the Prior EIR provided MM 4.N-7 to reduce the significance of traffic impacts, the Prior EIR still found that impacts would be significant and unavoidable under Cumulative Plus Project conditions. With implementation of MM 4.N-7, it was determined that the Housing Element would not conflict with the City’s adopted plans and policies as it relates to LOS and impacts would be lesser than what was evaluated in the Prior EIR. The Prior EIR also found that cumulative noise impacts have the potential to be significant. However, with the incorporation of MM 4.J-9, impacts were reduced to a less than significant level. Analysis of Proposed Project The proposed project could create a cumulative increase of regional air pollutant emissions, as noted under Section 3.III, Air Quality, of this document. However, according to Section 15064(h)(4) of the CEQA Guidelines,2 the existence of significant cumulative impacts caused by other projects alone does not constitute substantial evidence that the proposed project’s incremental effects would be cumulatively considerable. Rather, the determination of cumulative air quality impacts for construction and operational emissions is based on whether the proposed project would result in regional emissions that exceed the BAAQMD regional thresholds of significance for construction and operations on a project level. The proposed project does not exceed any BAAQMD significance thresholds, and therefore would not create a cumulatively significant impact. The proposed project could have a potentially significant impact related to geology and soils, particularly related to paleontological resources. However, implementation of MM GEO-4.D lays out a procedure for inadvertent discovery of paleontological resources, reducing impacts to a less than significant level. Furthermore, the proposed project would need to follow Geology and Soils Implementation Measures 1 through 3, requiring a qualified paleontologist to monitor all ground- disturbing activities. Lastly, prior to issuance of grading permits, the project applicant would need to conduct a design-level geotechnical study and incorporate all recommendations in the Geotechnical Exploration and design-level study into project plans. This would lead to a less than significant impact and therefore would not create a cumulatively significant impact. The proposed project could have a potentially significant impacts related to construction, operation, and traffic noise and vibration. However, implementation of MMs 4.J-1, 4.J-2, 4.J-5b, 4.J-5c, 4,J-6a, 4.J-6c, and 4.J-9 as well as Noise Implementation Measures 1 through 3 would reduce impacts to a
