After each review, the consultant will incorporate comments and input before the next <br />review. The following drafts will be developed, with each successive draft incorporating comments <br />from the previous review: <br />•First Draft to be reviewed by the City using an over-the-shoulder (OTS) approach. OTS <br />approach assumes a working document review that allows for early client input. <br />•Second Draft to be reviewed by the Technical Support Team (WSDOT Region, Headquarters <br />and FHWA staff). <br />The Consultant will meet with support team members as appropriate to resolve comments and <br />mutually understand the proposed methods and assumptions. When all comments have been <br />resolved to the City’s satisfaction, the Consultant will prepare a final Methods and Assumptions <br />document. <br />If as the project progresses, a change to the final methods and assumptions is proposed by the <br />project team or one of the partner agencies, the Consultant will coordinate with the City, and partner <br />agency if applicable, to determine if a change to the methods and assumptions is warranted. If the <br />City determines the proposed change is appropriate, the Consultant will prepare an addendum <br />describing the proposed change to the final methods and assumptions document. <br />Assumptions <br />Assumptions for this subtask include: <br /> While the previous I-5/US 2 Interchange Planning Study included both a technical and <br />Executive Support Team, the ARR is assumed to only include staff from City of Everett, <br />WSDOT, and FHWA.
