Chapter 3 Findings Regarding Project Alternatives Attachment "A" significant and unavoidable impact to the south Bristol Street/West Segerstrom Avenue during the five weeks in which Construction Configuration C.2 would be in place, this alternative would result in a LOS deficiency that would occur for approximately 65 days during construction, and would result in new significant unavoidable impacts due to the disruption of left -turn movements along South Bristol Street. Impacts to turn movements would not occur in association with the proposed Project. In light of these considerations, the City finds that Alternative Site No. 13 would result in an overall increase in near -term impacts to transportation /traffic, and rejects this alternative as infeasible because it would not substantially lessen any significant effects of the Project. (CEQA Guidelines Section 15126.6(b).) This alternative also is rejected as infeasible because it would fail to meet, or would not be as effective in achieving the proposed Project's objectives. This alternative would cause serious disruptions to existing business along South Bristol Street due to the need to construct sewer lines near the median, and would further disrupt the businesses within the shopping complex where this alternative site is located. This alternative would therefore fail to meet the proposed Project's objective of avoiding detrimental effects to existing businesses. 3.4.16 Alternative Site Location No. 14 (Alternative Site No. 14) 3.4.16.1 Summary of Alternative Site No. 14 Alternative Site Location Number 14 (Alternative Site No. 14) would involve the construction of a replacement lift station in the parking lot of an existing commercial complex located at southeast corner of the intersection of South Bristol Street and West Warner Avenue in lieu of the proposed Project site. Alternative No. 14 is located in the same general shopping center as Alternative Site Nos. 13 and 15, and would be constructed just northerly of the Chase Bank (2407 South Bristol Street). Alternative Site No. 14 is located approximately 0.50 -mile north of the proposed Project site. The location of Alternative Site No. 14 is depicted on Final EIR Figure 5 -1. The lift station that would be constructed at Alternative Site No. 14 would include a similar above- ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 14 would feature similar equipment and appurtenances as the proposed Project. This alternative would require the installation and operation of approximately 112 percent more underground sewer conveyance infrastructure than the proposed Project and it is anticipated that the duration of Construction Phase 11 would be increased by 64 work days (approximately 13 weeks) as compared to the proposed Project. The construction schedule for this alternative would otherwise be similar to the proposed Project. This alternative would not require construction activities within the South Bristol Street/West Segerstrom Avenue intersection or beneath the existing paved right -of -way of West Segerstrom Avenue (east of South Bristol Street). Therefore, this alternative would not require the implementation of Construction Configurations B.1, B.2, C.1, or C.2. However, this alternative would require the installation of new sewer facilities beneath the existing paved right -of -way of South Bristol Street that are not proposed as part of the proposed Project (i.e., to the north of the existing Segerstrom Lift Station). The segment of South Bristol Street between this site and the existing lift station facility contains a 20 -inch OCSD trunk sewer, a 36 -inch MWD pipeline, a 16- inch water main, and a SCE/MCI Duct Bank. These utilities would require special support during construction of the new 18 -inch sewer, as the new sewer line would need to be installed at a depth of approximately 16 feet, and this depth would increase with distance from the existing facility.
