Chapter 3 Findings Regarding Project Altemathres Attachment "A' 3.4.8 Alternative Site Location No. 6 (Alternative Site No. 6) 3.4.8.1 Summary of Alternative Site No. 6 Alternative Site Location Number 6 (Alternative Site No. 6) would involve the construction of a replacement lift station in the southern portion of a parking lot of an existing commercial center located at 2840 South Bristol Street instead of the proposed Project site. Alternative Site No. 6 is located approximately 0.15 -mile west of the proposed Project site, northwesterly of the South Bristol Street /West Segerstrom Avenue intersection. The location of Alternative Site No. 6 is depicted on Final EIR Figure 5 -1. The lift station that would be constructed at Alternative Site No. 6 would include a similar above- ground block structure as the proposed Project. In addition, the lift station at Alternative Site No. 6 would feature similar equipment and appurtenances as the proposed Project. This alternative would require the construction of 46 percent less underground sewer conveyance infrastructure than the proposed Project. As a result, it is anticipated that the duration of Construction Phase 11 would be decreased as compared to the Project. The new sewer lines required in support of this alternative would be constructed within the alignments of West Segerstrom Avenue (westerly of South Bristol Street), and within South Bristol Street (northerly of West Segerstrom Avenue), and would require the construction of a manhole within the intersection of these two roadways (thereby necessitating implementation of traffic control in a manner similar to Construction Configuration C.2). Development of a lift station at Alternative Site No. 6 also would require the City to acquire private property to implement a temporary construction easement, accommodate the proposed lift station, and provide easements for proposed sewer lines. 3.4.8.2 Summary Comparison of Environmental Effects As summarized in Final EIR Table 5 -1 and described in detail in RDEIR Section 5.4.8, relocating the proposed lift station to Alternative Site No. 6 would slightly increase the duration of the Project's near -term significant and unavoidable construction - related impact at the intersection of South Bristol Street and West Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00 a.m. and between the hours of 2:30 p.m. and 6:45 p.m. (Monday through Friday). In addition, development of a lift station at Alternative Site No. 6 would create new, significant near- and long- term impacts to transportation /traffic due to inadequate parking capacity. Near -term air quality impacts would be slightly reduced under this alternative due to a shorter duration of construction, and long -term odor impacts would be slightly reduced due to a slight increase in the distance to the nearest sensitive receptor. Near -term hydrology and water quality impacts also would be slightly reduced due to a smaller area of disturbance. Non -odor related impacts related to air quality /greenhouse gas emissions (long - term), impacts to noise, and impacts to utilities and service systems would be similar to the proposed Project. 3.4.8.3 Finding and Rationale for Alternative Site No. 6 The City hereby finds that specific economic, legal, social, technological, or other considerations make Alternative Site No. 6 infeasible. Specifically, Alternative Site No. 6 would not avoid or substantially lessen the Project's near -term significant and unavoidable construction - related impact at the intersection of South Bristol Street and West Segerstrom Avenue, which would occur between the hours of 7:15 a.m. and 8:00 a.m. and San Lorenzo Lift Station EIR (Project No. 06 -3510) 3 -15 CEQA Findings of Fact /Statement of Overriding Considerations 55A -54
