Exhibit 3 ■ ■ SAN LORENZO SEWER LIFT STATION 0 E ENVIRONMENTAL IMPACT REPORT S.0 ExEcUTNE SUMMARY clearly less than significant and that do not warrant further analysis in this EIR are addressed in Section 4.4, Effects Found Not to Be Significant. For each of the six subject areas analyzed in Section 3.0, this EIR describes: 1) the physical conditions that existed at the approximate time this EIR's NOP was filed with the California State Clearinghouse (April 12, 2010); 2) discloses the type and magnitude of potential environmental impacts resulting from Project planning, construction, and operation; and 3) if warranted, recommends feasible mitigation measures that would reduce or avoid any significant adverse environmental impacts that the Project may cause. A summary of the Project's significant environmental impacts and the mitigation measures imposed by the City of Santa Ana to lessen or avoid those impacts is included in this Executive Summary as Table S.1, Mitigation, Monitoring, and Reporting Program. This EIR also discusses alternatives to the proposed Project. Alternatives are studied that would attain most of the Project objectives while avoiding or substantially lessening the proposed Project's significant environmental effects. A full discussion of Project alternatives is found in EIR Section 5.0, Alternatives. S.2 PROJECT OVERVIEW S.2.1 LOCATION AND REGIONAL SETTING The proposed Project site is located in the southern portion of the City of Santa Ana, in the vicinity of South Bristol Street and West Segerstrom Avenue. It includes all ground area that would be physically altered by the Project's construction and operation. The Project site includes the location of the existing Segerstrom Lift Station, which is proposed to be abandoned and demolished as part of the Project. The existing Segerstrom Lift Station is located along the eastern side of South Bristol Street, approximately 250 -275 feet north of the intersection of South Bristol Street and West Segerstrom Avenue. The proposed Project site also is composed of an approximately 900 square -foot area north and adjacent to West Segerstrom Avenue, at the western terminus of San Lorenzo Avenue, which would be the site of the new proposed San Lorenzo Lift Station. Additionally, the Project site also includes the area of ground disturbance needed to install proposed subsurface sewer lines in South Bristol Street and West Segerstrom Avenue between the existing and proposed lift station facilities, and associated areas of roadway resurfacing. Refer to Figure 2 -2, Aerial Photograph, in Section 2.0. S.2.2 PROJECT OBJECTIVES, PURPOSE AND NEED The primary objective of the proposed Project is to provide a new sewer lift station to replace the existing Segerstrom Lift Station, which was originally constructed in the 1960s, most recently upgraded in 1989, and has since exceeded its design life. it has beeeflie inadequate to handle existing sewerage Pews and i obsolete i isen to fnedem lift station designs. Under existing conditions, the Segerstrom Lift Station is prone to frequent maintenance (two to three times per week) in order to clear blockages due to debris collected in the system. In addition, due to the age of the equipment, the existing pumps and other equipment are subject to frequent mechanical failure (requiring maintenance) and it is difficult to obtain necessary replacement parts for the existing g acility. The new pump station provides standby pumps in the event a pump is lost and includes grinders and a larger wet well to address debris within the collection system. Needed r-edundaneies asseeiated with the existing 144 st-Ation _ar-e inadequate in tha4 twe pumps are f `que ntly operated near eapeeity without a third standby pump —The provision of a new sewage lift station and associated infrastructure would ensure that sewage flows are adequately conveyed to wastewater treatment facilities while minimizing the risk of potential sewer spills. The following is a list of objectives sought by the City of Santa Ana in pursuing the proposed Project. PAGE S -2 55A -102
