DETERMINATION FOR SANTA ROSA STREET BRIDGE REPLACEMENT, SPECIFICATION NO. 93-44E. council j acEnaa aEpoin i CITY O F SAN LUIS O B I S P O FROM: Michael D. McCluskey, Public Works DirectoFoll� Prepared by: Barbara Lynch, Civil Engineer SUBJECT: Environmental. determination for Santa Rosa Street Bridge replacement, Specification No. 93-44E. CAO RECONEIIEIVDATION: Adopt a resolution approving the Mitigated Negative Declaration for the Santa Rosa St Bridge Replacement, Specification No. 93-44E. DISCUSSION Santa Rosa Street bridge was constructed in 1910 and is scheduled for replacement. The City has obtained Federal funding assistance to replace the bridge. In 1995 specialized studies, biological, archeological, historical and hazardous materials, were completed. In 1996, Community Development reviewed the project and the specialized studies and prepared an environmental document. At that time, mitigation for the project was specified (See Exhibit A). The Community Development Director approved a mitigated negative declaration which was made available for public review and comment on February 5, 1996 (ER 113-9 . No comments have been received. The environmental document prepared was based on a design which widened the bridge slightly to accommodate bike lanes and sidewalks. The Federal Highway Administration reviewed the project and the environmental assessment and determined the project met the conditions for a "Categorical Exclusion". Under normal circumstances the City would complete CEQA (California Environmental Quality Act) compliance at the time City Council approved plans and specifications for advertising. On projects such as this needing a California Regional Water Quality Control Board Certification, the Certification can not be issued until the CEQA process is completed. Because of this condition of the Board, we are requesting Council to take special action at this time to approve the mitigated negative declaration of environmental impact for this project. This will allow staff to prepare a complete bidding package covering all permit requirements. In addition to the Certification, the City will be obtaining a Fish and Game Agreement and an Army Corps of Engineers Permit before proceeding with the construction. Requirements from these three agencies include notification to the U.S. Fish and Wildlife Service and the Office of Historic Preservation. The project will still come to the Council for the approval of plans and specifications and the authorization to advertise the construction project. Staff expects design of the project to begin in November with plans and specifications to the Council for approval in late February or early March. Construction would begin in early summer of 1997. Construction will take about ten weeks. The issuance of the permits could delay the project either to the middle of summer or worst case, to the summer of 1998. ATTACE3 ENV'IS: 1.
