LSA ASSOCIATES. INC. CEQA INITIAL STUDY/LITIGATED NEGATIVE DECLARATION MARCH IPll PREDA STREET PIPE BRIDGES UPGRADE SAN LEANDRO. CALIFORNIA MITIGATED NEGATIVE DECLARATION Project Name. Preda Street Pipe Bridges Upgrade Project Location. The project site is located at an existing sewer pipe crossing over San Leandro Creek adjacent to Alder Creek Circle, near Preda Street, in the City of San Leandro. Description of Project. The City of San Leandro proposes to replace two existing sewer pipes and rehabilitate two supporting pipe bridges that span San Leandro Creek, to maintain flow capacity and improve pipe performance during future seismic and/or flood events. Proposed activities involve the following: removal of existing pipes, excavation associated with installation of pipe restraints, upgrades to the existing support bridges and installation of new infrastructure including new pipes and pipe restraints. Several potential pipe replacement alternatives were evaluated by the City of San Leandro. The proposed project was determined based on factors including cost, durability. maintenance, and minimizing environmental impacts. Based on the results of these evaluations, the City of San Leandro has elected to replace the existing bell- and - spigot ductile iron sewer pipes with new ductile iron, restrained joint pipes that can accommodate the anticipated displacement of the pipelines for all design criteria. Findings. It is hereby determined that, based on the information contained in the attached Initial Study, the Project will not have a significant adverse effect on the environment. Mitigation measures necessary to avoid the potentially significant effects on the environment are included in the attached Initial Study, which is hereby incorporated in this Mitigated Negative Declaration. The City of San Leandro Community Development Department has agreed to implement each of the identified mitigation measures, which would be adopted as part of the Mitigation Monitoring and Reporting Program.
