For Meeting of: May 16, 2017 ITEM TITLE: Resolution authorizing addendum no. 3 to the existing agreement with Golder Associates, Inc. for $16,670 to complete Modeling efforts for the Naches River that meet WS DOT requests as well as other agency requests during the permit process SUBMITTED BY: David Brown, Water/Irrigation Manager, 509-575-6204 Scott Schafer, Director of Public Works SUMMARY EXPLANATION: During a review of the City of Yakima's Water Treatment Plant I ntake Modification project with stakeholders, Washington Department of Transportation (WS DOT), and several other state and federal agencies, a request for a river hydraulic model was made to indicate flow elevation changes predicted from structures placed within the Naches River as part of this project. Permitting of the project also requires that a hydraulic model be conducted. The City already has an existing Professional Services Agreement with Golder Associates, I nc. pertaining to work with the City's Water Treatment Plant and is qualified to conduct the required hydraulic modeling. Addendum No. 3 authorizes the development of the required hydraulic model of the Naches River, including data review and model development, for a new intake structure and floodplain stabilization structures. The terms of Addendum No. 3 would be in an amount not to exceed $16,670. (See attached Addendum No. 3 with Exhibit "A" and "B") Exhibit "A" of the Agreement describes the Scope of Work in more detail. Exhibit "B" of the Agreement describes the Schedule of Rates in more detail.
