Chapter 3 Findings Regarding ProjectAiternathies Attachment "A" 3.4.2.3 Finding and Rationale for the Modified Construction Configuration C.2 Alternative The City hereby finds that specific economic, legal, social, technological, or other considerations make the Modified Construction Configuration C.2 Alternative infeasible. Although the Modified Construction Configuration C.2 Alternative would reduce the Project's significant and unavoidable construction - related impact at the intersection of South Bristol Street/West Segerstrom Avenue by a period of two (2) weeks, this alternative would result in new significant and unavoidable noise impacts for a period of two (2) weeks because construction activities would be required to occur during nighttime hours to allow sufficient time to set up and remove traffic control measures. Such nighttime construction activities would invariably result in significant noise levels that would impact nearby sensitive receptors, including residents of the nearby apartments and the Studio Inn Hotel. Such noise levels would exceed the City's Noise Ordinance requirements for nighttime noise levels, and would result in a significant and unavoidable impact to noise. In addition, and as discussed in EIR Section 3.4.7, modifying the timing restrictions for Construction Configuration C.2 so as to allow construction during the daytime while completely avoiding significant traffic impacts during the five (5) weeks in which Construction Configuration C.2 would be in place is not feasible. Specifically, during the three (3) weeks during the construction of a new manhole within the South Bristol Street /West Segerstrom intersection, Construction Configuration C.2 would need to be in place 24 hours per day. Accordingly, this alternative would reduce (by a period of 2 weeks), but would not avoid, the Project's significant and unavoidable impact to transportation /traffic. On balance, the City finds that the reduction in duration of significant unavoidable impacts to transportation /traffic that would occur under this alternative does not justify the significant and unavoidable impacts to noise that would result from the nighttime construction activities required for this alternative. Therefore, the City finds that the Modified Construction Configuration C.2 Alternative is not feasible. 3.4.3 Alternative Site Location No. 1 (Alternative Site No. 1) 3.4.3.1 Summary of Alternative Site No. 1 Under this alternative a lift station would be constructed at the western terminus of San Lorenzo Avenue (Alternative Site No. 1) in lieu of the proposed Project site. The location of Alternative Site No. 1 is depicted on Final EIR Figure 5 -1. Alternative Site No. I is almost identical to the proposed Project but would be constructed wholly within the existing public right -of -way of San Lorenzo Avenue and an unnamed public alley. This alternative would not require the acquisition of private property. Although the acquisition of private property that would occur as part of the proposed Project would not result in a significant environmental effect, construction of a lift station at Alternative Site No. 1 was selected in order to evaluate construction of a lift station on an alternative site that would not require the City of Santa Ana to acquire any private property. 3.4.3.2 Summary Comparison of Environmental Effects As detailed in RDEIR Section 5.4.3, relocating the proposed lift station to Alternative Site No. 1 would neither avoid nor reduce the Project's near -term significant and unavoidable construction- San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -6 CEQA Findings of Fact/Statement of Overriding Considerations 55A -45
