Administrative Draft Environmental Impact Report Gill Medical Center Project to connect the Project site with the nearest available water, wastewater and storm water utilities would occur within existing road right-of-way. Because trenching for pipeline extension could extend below previous grading conducted for road base construction, implementation of Alternative 3 would result in a moderate increase in potential impacts to paleontological resources. While implementation of Geology and Soils mitigation measures 4.9-5a and b could be applied during offsite utility construction, due to the length (and potentially depth for wastewater pipelines) of required trenching, a slight increase in potential for impacts to buried paleontological resources is expected. Therefore, Alternative 3 would result in a slight increase in potential impacts to paleontological resources and the proposed Project is considered superior for this issue. 6.3.7.4 Alternative 4: Alternative Site Location—Stockton Economic and Education Enterprise Zone (Eight Mile Road at 1-5) Alternative 4 would relocate the Project site to a suitable location within the City of Stockton Economic and Education Enterprise Zone located north of Eight Mile Road and east and west of 1-5 as shown in Figure 6-2. Existing conditions at the alternative site location are similar to the Project site in that it is mostly level and currently in agricultural production.Therefore, Project development at the alternative site is expected to be subject to geology and soils mitigation similar to that of the proposed Project. Because the alternative site is located within the City, development at the alternative site would include connection to City of Stockton utilities which would reduce the required construction footprint compared to the proposed Project. While this would result in a slight reduction for potential impacts to paleontological resources, both sites have similar geologic and soil conditions, and therefore the same paleontological mitigation measures are expected to apply at the alternative site. In summary, the only expected geology and soils advantage of development at the alternative site would be the slight reduction in construction footprint resulting from elimination of onsite utilities. Therefore, Alternative 4 is considered slightly superior to the proposed Project for paleontological resources. 6.3.8 Hazards and Hazardous Materials 6.3.8.1 Alternative 1: No Project Alternative Under the No Project Alternative, the proposed hospitals and medical office buildings, onsite circulation, parking, water, wastewater and storm drain improvements would not be constructed and the proposed Project medical services would not be offered at the Project site. Proposed Project Impacts related to the routine transport, use, disposal, or accidental release of hazardous materials during construction were found to be potentially significant. However, with implementation of Mitigation Measure 4.11-1a, this impact would be reduced to less than significant with mitigation incorporated. In addition, a former gas well was found to be located within the footprint of the Phase 2 Main Hospital building. This well was found to be a significant hazard to the public and/or the environment through reasonably foreseeable upset and accident conditions involving the release of Alternatives 6-16 October 2021
