Environmental Checklist and City of Pleasanton–10x Genomics Project Environmental Evaluation Initial Study/Mitigated Negative Declaration 22 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 The project site is currently zoned C-R (p), and the Applicant is requesting approval to rezone the site to PUD-C-O, which would allow R&D and light laboratory manufacturing uses on the project site.8 When a project includes an amendment to the zoning, inconsistency with the existing designation or zoning is an element of the project itself, which then necessitates a legislative policy decision by the agency and does not signify a potential environmental effect. As such, the proposed project would be consistent with the permitted land uses of the PUD-C-O zone upon approval of the requested zone change, and the rezoning would not result in an environmental impact. Upon approval of the rezoning, the proposed project would be consistent with applicable zoning and other regulations governing scenic quality. Impacts would be less than significant. d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Less than significant impact. A shade and shadow study was completed for the proposed project that analyzed the shade and shadow impacts of the proposed project during winter, summer, spring, and fall in the morning and evening (Appendix K). The proposed buildings would cast shadows to the northwest during winter mornings and to the northeast during winter evenings. In the spring and fall the proposed buildings would cast shadows to the northwest during the mornings and west during the evenings. During the summer, the proposed buildings would cast shadows to the west during the morning and to the east in the evenings. Most of the shadows cast by the proposed buildings would occur within the project site. The adjacent properties most impacted would be the surface parking lot to the northwest and the residential uses to the west. However, the shadows cast by the proposed building would move away from these areas in less than an hour and would not significantly impact these land uses. The existing development on the project site generates light and glare from parking lots, driveways, buildings, and vehicles. Pursuant to the City’s Zoning Ordinance Chapter 18.68, Planned Unit Development District, the City would ensure that the proposed redevelopment would be in the best interest of the health, safety, and general welfare of the public and that it would be consistent with City of Pleasanton’s General Plan policies regarding lighting and glare prior to project approval.9 Additionally, the proposed project would comply with Part 6 of the California Energy Code requirements related to outdoor lighting, which requires exterior light fixtures to be directed downward to prevent light trespass.10 The proposed buildings to be constructed during Phase 1 of the proposed project would be 68 feet in height and the buildings in Phase 2 and 3 would be up to 82 feet in height. The existing trees along Stoneridge Mall Road and Stoneridge Drive would shield existing uses from any light and glare produced by the proposed project. Additionally, the proposed project is anticipated to operate during typical business hours. Therefore, the proposed redevelopment would not substantially alter the existing light and glare on the project site such that the proposed project would adversely affect day or nighttime views in the area. Although Phase 1 may include expansion of existing surface parking areas, any new lighting required for these areas 8 City of Pleasanton. 2021.
