4 Environmental Analysis 4.2 Agriculture and Forestry Resources Additionally, PG&E would upgrade the Tesla Substation, and the improvements would include the installation of a grounding system, disconnect switches, surge arresters, outdoor lighting and outlets, and fiber termination for the gen-tie line. The improvements made would be within the existing Tesla Substation footprint. No additional farmland would be converted to make these improvements on PG&E's Tesla Substation property. The portion of the gen-tie line to be constructed by PG&E between the POCO and the Tesla Substation would be located outside of PG&E's property. However, the area where the gen-tie line would be located is not on land included in a Williamson Act contract, and the Williamson Act would not apply. Further, PG&E development of this portion of the gen-tie line would be consistent with the A zoning and LPA land use designation by Alameda County and the Alameda County ECAP, the same as previously discussed above for the portion of the gen-tie line to be constructed by the Applicant from the battery energy storage facility to the POCO, also within Alameda County. Finally, no forest land or timberland would be impacted by these improvements, as there are none present within the boundaries of the area that would be impacted. Accordingly, the PG&E Tesla Substation improvements and construction of the gen-tie line from the POCO to its substation would have no impact on significance criteria 4.2-1 through 4.2-5. No mitigation measures would be required. 4.2.7 Cumulative Impacts The Project would result in no impact with respect to conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance to non-agricultural use, and would not conflict with existing zoning for forest land or timberland. Therefore, the Project could not cause or contribute to any potential significant cumulative impact to these resource areas. The geographic context for potential cumulative impacts related to other changes in the existing environment which, due to their location or nature, could result in agricultural impacts is San Joaquin County. Ongoing impacts of past projects to Agriculture Resources are reflected in the existing conditions described in Section 4.2.1 and include the conversion of agricultural uses to other uses. The list of cumulative projects is included in Table 2-3 of Chapter 2, Project Description. There are no other projects that are under County consideration that, if approved and constructed, would have the potential to conflict with a Williamson Act contract or convert farmland to a non-agricultural use. With implementation of Mitigation Measure AGRA, Project impacts related to the conflict with the existing Williamson Act contract on the San Joaquin County portion of the Project site are less than significant, site specific, and not expected to result in the conversion of other Williamson Act contracts. Additionally, the Project would not contribute to a cumulatively considerable impact, as there are no reasonably foreseeable conflicts on other properties, based on the list of known cumulative projects. The Project would have a less than significant indirect impact related to potential conversion of adjacent offsite farmland to non-agricultural use. Because this incremental impact could contribute to a potential significant cumulative impact, the County has considered whether the contribution would be cumulatively considerable.
