SII C I T Y OF SAN LUIS OBISPO FROM: Michael D.McCluskey, Director of Public Works f- Prepared By: Barbara Lynch, Civil Engineer SUBJECT: FOOTHILL BRIDGE REPLACEMENT ENVIRONMENTAL DESIGN CONTRACT, SPECIFICATION NO. 90197A. CAO RECOMMENDATION 1. Approve Amendment 5 to the Agreement with Martin; Rivett & Olson (MRO) for design and other services on the Foothill Bridge Replacement Project and authorize the Mayor to execute Amendment 5 upon receipt of the signed amendment from MRO. 2. Authorize the City Engineer to execute future amendments up to $24,000 (the remaining balance in the design account) in order to complete design, environmental work, and right of Way activities in a timely manner. DISCUSSION MRO, the design consultant for the Foothill Bridge, is nearing completion of the various tasks necessary to bring the bridge project to construction. Over the duration of the contract, Public Works has authorized two amendments for additional work, including preparation of permit applications, acquisition of clearances from the Federal Emergency Management Agency, and design of various minor refinements. One amendment simply authorized commencement of right of way work at no additional cost. Another amendment reduced costs because the City contracted directly with subconsultants in order to expedite progress on the project. Amendment 5 covers revisions to the construction easements needed after review of the easements by an appraiser. These revisions will minimize impact to adjacent property owners during construction. The Army Corps of Engineers requiresadditional study of the flow characteristics of the new structure before it can issue a permit for the project,and a review of the appraisals for the acquisition of the temporary easements by another appraiser is now a condition of the federal funding. This requirement represents about half of the additional costs of this amendment. Public Works is also recommending expanded authorization for the City Engineer to approve additional work for design, environmental work, or right of way up to the limits of the existing budget for design. This will expedite any further amendments needed so work can be proceed on schedule. FISCAL IMPACT The cost of Amendment 5 is $10,030.
