Please reference the attached Supplemental Agreement No. 1 from McMahon <br /> Associates, Inc. dated March 18, 2016 for a detailed scope of signalization design and,permitting <br /> set-vices. All provisions of the original Executed Work Order No. 1- Engineering-Dated 4/14/2015 shall <br /> .remain in full force and effect. I <br /> CAI Scone: <br /> The previous 41" Street / US 1 intersection design consisted of reconstructing'US 1.to provide a i <br /> plateaued intersection in all four directions. (Note: The design and permitting work for the US 1 i <br /> reconstruction is near 90% complete). The revised design will eliminate plateauing.the intersection <br /> and reconstruction of US 1. The revised design will tie the proposed widening of 41 St Street to US 1 <br /> on the west side of US'1 joining at the existing grades._As in the previous design,41St Street will be <br /> 1. <br /> completely reconstructed west of US l.to the western extreme of the proposed improvements. The <br /> previous design will remain unchanged for improvements in Old Dixie Hwy and 41"-Street west of <br /> Old Dixie Hwy. Tasks anticipated to be completed by CAI for the redesign and permitting of the <br /> project include the following: <br /> • CAI will meet with COUNTY engineering staff as needed to define design criteria and <br /> resolve any design or permitting issues, CAI will prepare a conceptual plan view of the <br /> redesign and will meet with COUNTY engineering staff to review the plan which will <br /> become the basis for the preparation of detailed construction plans and re-permitting of the <br /> project., <br /> Servu Florida <br /> since loll <br /> N:\PSW\P\14-84EIRC4lstStUProposals\RevAmendment2Proposal4-5-2016.doc Page 1 of <br />
